BTNet Leased Line with Unifi Dream Machine Pro

Hi

I had BTNet 1000Mb leased line installed on Monday. I have a single-mode fibre cable from the exchange dropping into an ADVA NTE box (FSP 150-GE102Pro), and offering a multimode sfp connection for me to use (I was expecting an ethernet port to be honest). This is the first leased line we've had and I'm a bit confused about connecting it to my UDM-PRO (bought as this has a WAN SFP port).

I have used a 10G SFP module (UF-MM-10G) in the UDM-PRO and connected the kit using a multimode LCLC cable.

When powering up the UDM-PRO it attempts to automatically detect internet and when that fails I can choose the SFP WAN port, enter the IP, Gateway, subnet mask and DNS server details. However, this still doesn't connect.

Any idea where the issue may lie please?

Thanks!

If you have a 1G service (1000 Mbps) why did you buy a 10G SFP ? The SFP's that I have used are not switchable, only work at the speed on the packaging. I suspect you will need a 1gig SFP.

Others may know more.

Hi,

Thanks for the response - I've not used SFP before and assumed that the higher the better and they'd be backwards compatible. I note from the spec of the ADVA box here that the SFP fitted is 10/1000 https://www.adva.com/-/media/adva-main-site/resource...

I have ordered new 1 gig module which will be here tomorrow. Hopefully that may resolve it!

Thanks again

They're not, and at 10G there are multiple standards to choose from as well.

For a 1G SFP you should be paying less than £10 each. fs.com is a good source for these.

You need to check with your supplier which standard to use to match the ADVA box facing you. There are two likely possibilities:

- 1000baseSX, which is multimode-only
- 1000baseLX (sometimes called 1000baseLH), which works on multimode and singlemode

You need the matching SFP on your side.

If you pull out the end-user-facing SFP from the ADVA side you may be able to work it out. With luck it will say the wavelength: around 800nm then it's SX, and 1310nm it's LX.

That's brilliant, thanks so much for the info. I think we have found where the issue lies.

I'll check the module in the ADVA box when I'm on-site later and with a bit of luck it'll be compatible with the 1 gig module I have on order!

Thanks again.

I don't have quite the same setup, but I had to hard reset my UDM-Pro back to factory to get it to detect the connection, may be worth a try.

Thanks - I'll give it a go. I upgraded to the latest and greatest 1.8.0 firmware and sadly the setup process on that is goosed so I'll have to downgrade it.

I have been using a UDM-P on consumer BT since January with a mostly positive experience.

Note that some people (including me) see a significant throughput hit when using IPS/IDS. This is thought likely due to the PPPoE connection to the ONT, so may not affect you - I would be interested to hear if you have issues

Also, you *may* find it helps to manually set the speed on the SFP WAN port - this is sometimes needed on the LAN side though I haven't heard of anyone using the SFP WAN so can't say for sure

Thanks for your reply - I'll do some testing when/if I ever get this thing online!

A pair of matching generic SFP’s from fs.com with the appropriate matching LC ended fibre patch lead will get you out of trouble for less than £20 all in.

Alternatively if both boxes are immediately adjacent to one another get a gigabit direct attach (DAC) cable from somewhere like Amazon for a similar outlay.

In this way you can be sure that both ends match. Just don’t go getting a SFP+ modules instead of SFPs by mistake.

The interface specifications are detailed in SIN360 and SIN492. Until recently the handover from the Openreach NTE was optical only, either 1000Base-SX or 1000Base-LX depending on what was ordered, with the demarcation point being the duplex LC connector - they may not take kindly to their SFP being replaced.

I've not ordered an EAD circuit recently so I don't know if the NTE will switch between SFP and 1000Base-T automatically, or if the copper interface has to be specified in the order.

As said above then, the OP may as well just pop the SFP out to check it’s LX, SX, ZX or whatever and buy another matching generic SFP from fs.com and the requisite duplex patch lead.

For the cost of a flat white in London a generic SFP can be had from fs.com, so you may as well buy a pair, and you can be certain they’ll be compatible across the link. The SFP cage won’t tell the demarc. cops at BT

In theory it could. It could be vendor-locked, or they could be monitoring it with DOM and notice the change in device / serial number.

That reminds me, it's worth buying an SFP with DOM. It may be the same price, or only £1 more, but if your router supports it it can give you all kinds of info such as light levels. (Not that over a 1m patch cord it's likely to be a problem)

The cage won't, but the DDM/DOM data might give it away

At light levels over a one metre patch, it will be asking for sunglasses!

It isnt vendor locked at least from the BT end.

My advice is to make sure you have a compatible SFP and make sure you are using your WAN address (should be a /31 subnet) sometimes BT can forget to send this out. If you need that info, call the number on the emails you've been getting and if the person on the phone cant give you that info, ask for the number for the commissioning team

All the SFPs I’ve bought from fs have been DOM for ages. If the OP buys a pair of these:
https://www.fs.com/uk/products/75332.html
...and one of these:
https://www.fs.com/uk/products/41730.html

The total (with VAT and shipping) comes to £26.40

Alternatively plug and play is to buy a gigabit DAC cable from Amazon for £20.99:

Sorted for the basic link between boxes. Then just do the WAN ip config

Just in the process of getting ours installed today. Again an ADVA FSP150-GE102Pro unit as per the OP. Openreach fibre's not quite installed, so just pulled the SFP's in the NTE out to have a quick squiz.

Network SFP is an Adva 1000BaseBX10 BiDi optics, 1310nm receive and 1490nm transmit with simplex SC presentation.

Access SFP is an Adva 1000BaseLX 1310nm single-mode with duplex LC presentation.

When we're up and running I'll swap out the LX SFP above with a generic 1GB DAC cable direct to our router, to see if the ADVA grumbles.

They will be ten digit numbers, something like -- 0061003015

I've got a link working with the supplied SFP. I'll try out the DAC, possibly tomorrow, at least initially to check the link comes up. Service is not live yet.

Not properly, as the install was stalled for a few days last week whilst external cabling issues were sorted.

Openreach have been back in again this morning completing the internal fibre cabling from the external/internal splice point to the cabinet. Fingers crossed, will hopefully be able to test properly later on.

What SFP interface have you actually ordered with your service?

I've ordered the 1000/1000 service from BT and I specifically asked if they would let me use the RJ45 on the ADVA to my router. Let's just say I didn't get a clear answer. I'm never going to go above 1000/1000 with BT, as it's a backup line to my other leased line with Virgin.

So to cater for everything, in case the RJ45 is not enabled, I have ordered the 1GB 10GTek DAC as mentioned in the thread, and I also ordered a 10GTEK 1GB to 1000Base-T.

https://www.amazon.co.uk/10Gtek-Gigabit-SFP-DAC-Cabl...

https://www.amazon.co.uk/SFP-GE-T-1000Base-T-Transce...

I'll be plugging into an EdgeRouter 12 which I've mostly configured already on the RJ45 port, but can easily switch to SFP port if that is going to be required. I'm pretty confident that both the DAC and SFP will work with the EdgeRouter, but whether it works with the ADVA is the big unknown.....

The Adva *might* work with either the built-in RJ45 port, the DAC or the 1000baseT SFP. Fingers crossed for you that it does.

However, the much better (and cheaper) solution would have been to buy a 1000baseLX SFP to plug into your Edgerouter, and an LC to LC single mode duplex fibre patch cable (LX = single mode). From fs.com that would have set you under £10 in total, plus postage.

More importantly, it leaves the demarcation point in the Adva exactly as BT supplied it, and there's no risk of setting off alarms in their monitoring systems for replacing the customer-side SFP that they installed.

Apologies for not providing an update sooner, but the internal cabling today, which started out quite straightforward, ended up going horribly pear shaped by the end of it. There’s still no service running, so I can’t really test the interoperability of different pluggables on the ADVA with a live service.

If you ordered an LX class SFP with your service then easiest thing as candlerb says is to get a matching 1310nm LX SFP for your router and a duplex LC single mode patch lead.

Thanks both.

Ignoring the price, would this be the one?

https://www.amazon.co.uk/10Gtek-Singlemode-Transceiv...

and this with it

https://www.amazon.co.uk/Fibre-Single-Duplex-Gigabit...

Always buy via Amazon and don’t mind paying a few extra quid.

Affirmative.

Probably a bit OT but i thought the SFP port was only live on a gigabit circuit?

IE, if you order 100/100 it would only be the RJ45 available to use?

You may be right, but as I mentioned above I've ordered the 1000/1000 service, not 100/100.

I almost want the reverse. I WANT the RJ45 port enabled, rather than SFP, as I will never go above 1000/1000. I accept that in reality it's about 940/940 due to this anyway.

The Bearer is nominally 1G. Access is any rated fraction of that. How would they otherwise deliver a 500M circuit for example.

The corollary is Opensheep delivering say 330/30 FTTP on an ONT that uses straight 1000BaseT copper port. Your connection to the gateway is 1000M but your effective WAN connection is 330/30.

I have a BT/IDNet 1Gb leased line with a UDM Pro, tried with a DAC cable today and I get a link but the UDM Pro will not detect an internet connection.

Also FYI the RJ45 port is disabled on the ADVA by default when you order 1Gb, I asked if they could enable but they said no.

I've ordered a SM SFP and cable to try tomorrow with the ADVA SFP that was supplied.

Oh dear, that's not great news. I've ordered the SFP and patch cable as well based on your experiment.

Do you have to use pppoe to authenticate?
I ask as there is still an ongoing issue with reduced throughput on pppoe connections, I can only get about 6-700Mbps on my cityfibre/vodafone 900Mbps connection on a udmp.
Even on latest 1.9 firmware its the same.
I dont use the udmp as my router as its still a shockingly bad piece of kit, enterprise it certainly isnt, I just take it out now and again to try new firmware versions in the hope they add things that have been asked for since it came out.

No, BTNet is a static IP address setup with no authentication

There’s definitely no PPPoE on (wires only) leased lines provisioned by Openreach.

I have PPPoE but only on Openreach based FTTP. Which is of course an entirely different product.

Not yet. We have had an internal cabling nightmare!

There is a 12-core blown fibre cable that comes in from the street, terminates in a fibre splice enclosure. From there Openreach pulled in a 2-core fibre cable to the equipment cabinet, using a roped run into a flex-coiled duct running in the finished floor void space. At some point there must have been too much stress on the fibre cable whilst pulling it into the ducting, causing the fibres internally to fracture. That wasn't known until it was all spliced up both ends.

It was clear after testing/OTDR, the internal fibre was fecked, so as a workaround they decided to pull in a new dual micro duct in as a replacement and then blow in a fibre from the splice to the cabinet fibre tray - using the old fibre cable as a draw. There was however another coax cable pulled in together with the fibre, and this cable was left in the duct rather than being pulled through. Unfortunately I think this was a bit of an error as the new micro-duct then became jammed up as part of running it in.

Then in the process of trying to pull through the new microduct, either the redundant fibre or the micro duct broke/separated on the pull-in. Leaving a part run bit of micro duct that now stubbornly refuses to be pulled back.

So currently looking at alternatives to get a fresh micro duct installed in a new pathway, but it is quiet messy and involved as all the walls, floors etc are final finished and closed up. We think we have found a viable alternate pathway / void space, but I'm waiting on electricians now to attend to open up walls and fish this through properly.

Yeah, not quite what was expected, but that's life!

After 4 days of troubleshooting I have my 1GB leased line up and running through the UDM Pro. It was actually just a config issue at IDNets end...

I tested the original DAC cable and also worked fine since the beginning.

I troubleshooted through 6 SFPs, 2 routers and 4 different fibre cables.

Can't believe it!! I need a beer.

I guess IDNet did not believe me when I told them the line was not working.

Are you using the built-in switch on the Pro? Not sure if you know, but it's apparently only got a 1Gb backplane so may limit your throughput it you use it.

Well done. What DAC did you test with? Did your port LED's on the ADVA change from red the link from ADVA to your router was active and passing traffic?

Me I'm still in internal cabling hell. Talk about Murphys Law. Hahaha

As the uplink is 1GB anyway didn't think this would be a problem, if it becomes one though i'll just use the other SFP port to connect to an external switch and run the network off that.

The way I understood it is to imagine the built in switch as an external switch with a "1GB cable" (which it kind of is via pcie) to the uplink.

The network clients can still all communicate to each other at 1GB simultaneously, it's just the connection to the uplink is only 1GB to share between them, which is fine as it's only a 1GB connection anyway.

Used this one - https://www.amazon.co.uk/gp/product/B07HGX1751

Ports on the ADVA were always green with the DAC connected, just never received any packets from it. IDNet constantly made me believe it was my cabling/SFPs, but 4 days later they said something was setup wrong due to human error on their end.

Thanks. I could've sworn the ADVA SFP link on mine went from red to green when I first connected an SFP and fibre patch-lead back to the router.

Whilst waiting for engineers to sort cabling out, I then swapped over to a DAC (same Amazon sourced 10Gtek brand as yours) and it was definitely red.

Went back again to SFP, but moved the ADVA brand SFP into the router and used the router's SFP (fibrestore) in the ADVA - link stayed red.

Now moved back to the original setup - ADVA link is still red. Although router is reporting link up and healthy Tx/RX power levels for all combos above.

Weird - perhaps no WAN link on Network port is causing the ADVA grief. Anyhow its all moot for now until the network fibre finally gets to the ADVA...

Thanks for your thoughts. Quite possibly.

I don’t know really enough about the ins and outs of how ADVA’s behave in such a scenario. If so you would think it wouldn’t have brought up link (green LED) in the first place though...?

Hmmm anyhow it’s possibly all rather pointless and academic until the network link is present. It’s a chocolate fireman for now. If it’s still doesn’t work when we haul the new fibre through, it will need some real investigation.

Just had my OpenReach survey done this morning.

It turns out I'm 20 metres from the optical node, so he said he'll have it installed in a couple of weeks......

As soon as it's in, I will be testing DACS, SFP-1000BaseT, and other SFPs to feed back.

Fingers crossed for you, that's sounds like good news for your FTTP service! Don't get confused though with the subject matter in this thread is all about leased line services - completely different animal altogether.

Your FTTP service will simply terminate on either a little cigarete packet sized Huawei or Nokia ONT.

The only available interface is a regular 1000BaseT RJ45 port. No DAC's or SFPs required...just a Cat5e/6 cable!

No No, this is BTNet wires only 1GB/1GB terminating into an ADVA.

Ah my mistake. When you said optical node I presumed *wrongly that you were talking about an FTTP/FTTC aggregation node.

Good news anyhow.

Yes sorry, I'm not exactly sure what he called it, but basically where he will connect my new fibre from is 20 metres away and he lifted all the lids and I have ducting all the way to my exterior wall. The current ducting has a 20pair copper to my building, but plenty of room to pull the fibre. Interestingly he said it wont be blown, but pulled through.

I believe they term it a mini-node. We have one now installed outside in the footpath chamber. They blew a 12-fibre 'bundle' from there to the next nearest mini-node about 150m away. It then runs another 700m approx. to the main node which runs back to the local exchange.

Unfortunately for us the biggest (totally unexpected) drama has been the internal cabling. Which I'm still trying to get resolved...

In reply to a post by alanplum241276:

As I understand it, blowing is normally done through subducts: tubes with a bore only slightly larger than the fibre cable.

In some case they will pull a subduct, and then blow a fibre cable through that.

Openreach will often blow the fibre internally also.

Here is a section of twin tube Mark 3 BFT internal grade twin 3.5mm (internal bore) /5mm (external diameter) courtesy of Openreach. From the outside it just looks like regular twin and earth...the actual blown fibre bundle (12 fibres) is tiny not much bigger than a single core coated fibre.

There’s definitely no PPPoE on (wires only) leased lines provisioned by Openreach.

I have PPPoE but only on Openreach based FTTP. Which is of course an entirely different product.

Has OpenSheep sorted yours out yet?

Internal cabling (or should that be tubing) nightmare was sorted yesterday finally. New BFT duct all run.

Openreach were back this morning and literally pushed in the blown fibre bundle from the external splice to the fibre tray.

We are finally physically connected back to the exchange this morning, now waiting on carriers tests and commish to complete....

I'm getting my fibre installed tomorrow from the mini node.....

Fingers crossed all my internal ducting is good

Here’s a (hopefully) good omen for you; our final commissioning took place this morning. Had I had the VLANs IDs could probably have been dusted late last week, but we’re cooking with gas (hydrazine!) now....

Question is.....did you use the 10Gtek DAC?

Short answer is no, not (so far) tested on a live service.

Only tried it on access whilst we were waiting for the network side to be completed. At that point we did get link up (solid green LED on ADVA and frames passing on router side), but it later appeared to drop back to Red on the ADVA which as was pointed out was probably just due to Link Loss Forwarding, as network was down.

This is an ethernet leased line service,1 Gbps access on a 1 Gbps 'bearer' which is not a straightforward or direct comparable to a broadband service which is shared/contended. There are also stricter service levels and response/fix times being a business service. Unfortunately this makes it quite a bit more expensive than say FTTP. However where this circuit is located there is no possibility of any sort of FTTP, FTTPoD or even FTTC, nor any other Alt Net providers (currently though that may change)

There are many companies out there that will provide (re-sell) leased line circuits which in turn are typically bought through one of the large wholesalers. The final 'tail' or connection between the premises though is typically provided by one of the large established telco's which may already have the fibre in the ground and the connectivity at a local Point of Presence (like a BT exchange) - i.e. the likes of Virgin Media Business or Openreach.

Of course you can order such a service directly from BT, but you are better off shopping around as the actual rental prices, excess construction costs etc vary quite massively between providers and also depending on where you are in the country. There is no one size or standard price.

If you are contemplating this seriously, PM me and I can put you in touch with different providers that quoted at the time.

Well it looks like I have the opposite problem to you Pheasant....

All my internal fibre is in and tested to the mini node (well past it actually), but apparently, it goes via 6 nodes, and all the fibre bundles need to be peeled back or opened or something he said.

No timescale given

On another note.....the 10GTek DAC gives me a green link from the ADVA to my EdgeRouter, That's nice

Heres a picture....excuse the mess, but circled in green.

Don't worry had the same sort of external cabling issue here; there was a 7-tube micro-duct from nearest mini-node (TMBERKM for the Openreach folks) to next node (TPPG) here that was blocked. They spent most of the first day trying to resolve it. Eventually they sorted in about 3/4 days or so later - that was an 800m-ish run...

Keep an eye on the ADVA access port LED. Will be interested to here if yours goes red eventually (suspect as there is no network link present upstream and LLF takes effect).

I'm not tinkering with this one for now, getting other internal VLANs sorted currently...

Thanks, I did get a quote for a similar service (not sure if the same or not) from BT direct, but their opener was round £600/pm with a 5 year term inc a Cisco router. It struck me as being expensive at the time.
Probably best let the dust settle on the forthcoming FTTP.

One of the resellers is linebroker.co.uk, you can get a quick idea of the current costs there. You should not need to take any contract longer than 3 years (BT are the ones who take the mickey by asking for 5 years).

Thank you After a bit of googling and sifting through folk who don't look like brokers at all I did get to that linebroker site that does give an idea of current costs and appears to be quoting the bulk of the suppliers, it was very useful. The BT quote & term does now look confirmed like a mick-take.

I'm surprised how little extra the dedicated 1G symmetrical link is above the cost of the 900/200 FTTP options from the few vendors who offer it, considering the contended nature of FTTP.

They’re not too bad for a ballpark. But there’s better to be had. The name is also rather a confusing misnomer as they’re not really a comparison website or in truth “broker”, but as you say a reseller that are offering circuits from various carriers etc. The name draws in the punters.

End user charges are very much location/area dependent. If your in the centre of a large city there’s usually plenty of fibre nearby and therefore the ECCs are manageable under a 3 year deal. The costs are typically absorbed into the cost of the deal, so there is nothing up front to pay. A 12 month deal will typically see you paying for the ECCs. Of course out of town centres or areas where there is little or no fibre presence with ECCs can easily reach £100K+. Even £200k isn’t unheard of.

In any event in the IT and comms market unless your presented with some astonishingly amazing deal, as a small business. You shouldn’t contemplate locking yourself into a 5 year deal. The vast majority of deals are 3 years and that’s usually plenty as the market evolves.

Edit: just had a quick look at Cerberus costs for 900/200 FTTP @ £180 pcm with a £495 install charge. The best wholesale cost a 1G on 1G leased circuit is around £280 pcm, on top of which a reseller will add their margin. As said though quite different products in reality.

Yes, at the point 5 years was mentioned I pretty much switched off... I guess they must catch enough for it to be worth it.

That's partly why the 1000/220 level is so expensive: not because it costs any more to provide (the upstream bandwidth is effectively free), but because Openreach/BT don't want to eat into their leased line market, and to discourage heavy users on the PON.

If you genuinely need 1000/220 then indeed it may be worth paying the extra for a leased line. Otherwise, FTTP 500/165 or 1000/110 are cheaper, and only tie you in for 1 year.

So the ADVA link port is still up and green. I wonder if LLF isnt kicking in due to the fact the Network side isn't plugged in. (Currently has a red light device on it to trace the fibre through the nodes)

This also presumes that FTTP/FTTC is available as an option, which for example in EO areas it isn't.

12 months or 3 years are the usual contract lengths. Obviously with the exception of BT....

Personally unless you're in rented premises with a lease term under 12 months, I don't really see the point of a12-month leased line contract, as they will simply insist on payment of ECC's which will could typically be a few thousand pounds up front. Which they otherwise absorb (again typically up to £3 -5K).

Beyond that I cant see why anyone would sign up for a 5-year term, especially in these times.

I got to the same conclusion, only if you knew you had to vacate at a point in time would it ever make sense to do the 12 month route, and who wants to be tied in for 5 years...

Openreach have now resolved the issue for me, so I now have an Orange LED (rather than red) on the network side of the ADVA. I guess I just need BT to "switch it on"

Still have a green LED on my side using the 10GTek DAC....never did go red, so perhaps its an Edgerouter vs UDM Pro thing for the LLF?

Anyways......I'm a happy chappy and can't wait for it to be turned on now.....

Good stuff. Hopefully that network light goes green soon.

The SFP cage won’t tell the demarc. cops at BT

In theory it could. It could be vendor-locked, or they could be monitoring it with DOM and notice the change in device / serial number.

That reminds me, it's worth buying an SFP with DOM. It may be the same price, or only £1 more, but if your router supports it it can give you all kinds of info such as light levels. (Not that over a 1m patch cord it's likely to be a problem)

it's not, but if your circuit is ordered as Multimode presentation, only multimode will work. if you order singlemode presentation, then only singlemode will work.

The Copper port is 10/100 only and wont be used on circuits above a 100mbps bearer

Surely if you change the SFP in the access side from MM to SM then it will still work?

For example, I was supplied with a MM SFP from OpenReach, but I'm currently using a SM DAC and I have a green link. Just removed the MM SFP and put the DAC in.

I cant confirm 100% that it works yet, as I'm still waiting for the network side to go green.

The ADVA port is gigabit. If a gigabit bearer is ordered then it will be presented as fibre, but if the bearer is ordered as 100Mbps and installed after 2017 it can be remotely upgraded to gigabit by Openreach, at which point the copper port will negotiate at 1Gbps.

Wonder if any CP's take advantage of the copper port for Gig service for their 'wires only' customers? It was never mentioned in my case.

Its not widely advised or published that I'm aware of - the clear steer for wires only only is to the SFP port which is more adaptable anyhow.

I don't think you can actually order a gig bearer with a copper handoff, it's just for the situations where a bearer is being upgraded. The idea is that an ISP can sell a customer a faster speed without any physical changes needing to be made.

Ah I see. Couldn’t get to the explanatory notes in your link above.

Well unfortunately I'm still without service.

OpenReach has gone back with a successful "fit and test" but apparently BT are having issues with the "Data Build"? Something to do with adding a table at the exchange?

Does anyone actually know how to decipher that?

Thanks

Sounds to me like BT haven't finished building the layer 2/3 stuff; VLANs and/or IP addressing on their routers. Is the network light green?

Network LED was green here several days before handover. I think on my circuit they had time to complete all configs, whilst I had the (somewhat unexpected) internal cabling issue, which took a few weeks to resolve. When we were finally spliced up everything was "there" pretty much.

Looks like amber LED on ADVA could be any of following. Suggests that the network link build/config hasn't been sorted yet

Sounds reasonable. I have been constantly pinging the BT transit address (my next hop) from a different provider and it’s not been pinging. I can only assume that once it starts pinging the network LED will go green.

I’m not using BTnet but Virtual1, so it’s going to vary somewhat, but I had to complete the VLAN setup for both WAN address ranges before traffic would route. I could “see” various other hosts from the router on layer 2 arp but as said traffic didn’t pass until that config was complete (and I set up my default routes, gateways etc on my router)

BTNet doesn't use VLAN's on the WAN interface, so I haven't needed to do that.

Annoyingly, with BTnet you can track the progress of the order but they just keep pushing the "Target Date" forward more and more every time I call up for an update....

All I want is to confirm that the 10Gtek DAC works!!!

OR installed the fibre end to end on March 9, and then handed over to BT, so it unfortunately a case of waiting for BT at the moment.......

I raised this order originally first week of January

10 working days typically is what’s quoted. So you should be up and running soon 🤞

I got all excited tonight as suddenly one of my transit IPs started pinging.

BT give me a /31 transit address for the WAN which my /29 block is routed.

After some testing it looks like they’ve put MY IP on their end instead of theirs!

It’s like pulling teeth this commission. I was allocated a.b.c.10/31 for my WAN, and a.b.c.11/31 as my next hop. a.b.c.10 is pinging, but it’s not originating from my end. IPv6 the same, they used x:y:z::708/127 (mine) instead of x:y:z::709/127 (theirs).

I tried reversing my end just in case but no joy.

Goodness knows how this one will get resolved.

I think the fastest, most efficient way to resolve would be to get someone on the phone from BTNet to review the config with you, whilst your both monitoring the circuit and checking traffic.

That’s slightly non-conventional. I would have expected to have the gateway/next hop as the first IP (in ascending order) in a given subnet. Of course in reality any valid IP in the allocated subnet could be the next hop.

For what it’s worth my main allocation is a /29 block (on a particular VLAN) and a separate /30 (different VLAN). The routing on my box is based on gateway/next hop as the first/lowest useable IP in each given block, with the “useable” IPs then assigned in ascending order up from the gateway IP.

This is what was sent to me: (masked obviously)

IPv4 Directly Connected Section:
IPV4 Network Address : a.b.c.10
IPV4 Network Mask : 255.255.255.254
IPV4 BTnet NTE Router LAN Address : e.f.g.193/29

The 'IPV4 BTnet NTE Router LAN Address' is your default gateway.
The 'IPV4 BTnet NTE Router LAN Address' + 1 is your first useable address and should be configured on your equipment.
The same format should be followed for IPV6 if you are using those addresses.

IPv6 Directly Connected Section:
IPV6 Network Address : x:y:z:1000:0000:0000:0000:0708
IPV6 Network Mask : /127
IPV6 BTnet NTE Router LAN Address : e:f:g::1/64

Information for your subnets that are not directly connected to your BTnet connection:

IPv4 Non-Directly Connected Section
IPV4 Network Address : e.f.g.192
IPV4 Network Mask : 255.255.255.248
IPV4 Next Hop Address : a.b.c.11

IPv6 Non-Directly Connected Section:
IPV6 Network Address : e:f:g::
IPV6 Network Mask : /56
IPV6 Next Hop Address : x:y:z:1000:0000:0000:0000:0709

I just checked my Virgin Leased Line and it also uses the lower (first IP, albeit a /30 on VM) in the transit for the NTE end and the higher IP for the VM end.

So for IPv4. your router should have the e.f.g.193/29 address range setup.

The gateway/next hop on your routes should be e.f.g.193. Ensure that’s in your default 0.0.0.0 route.

Your first usable IP is e.f.g.194 (that is your pingable WAN address on your box) followed by e.f.g.195 to e.f.g.198

For the LAN side of my router, yes it is.

My topology is ADVA->EdgeRouter 12->UDMPro, Watchguard.

The UDMPro and Watchguard have public IP's no NAT, DMZ, and Edgerouter configured as such to pass all traffic.

My WAN interface on the ER12 is the .10/31 (nexthop .11/31), and my LAN switch is .193/29

According to the documentation, my /29 is routed via .10/31 so this seems correct to me.

This is exactly how my VM leased line is configured.

Edited by alanplum241276 (Fri 19-Mar-21 08:25:35)

I should probably add this is "wires only" from BT. No managed router, hence why I have the transit addresses for my EdgeRouter.

If you think BTnet have swapped .10 and .11 around, then the way to test is to traceroute to .11 from the outside.

If they've got them the wrong way round (and the link is up), then you'll see the packet loop between .10 and .11

- datagram arrives at BTNet; BTNet thinks .11 is at customer end; forwards to customer
- datagram arrives at customer; customer router thinks .11 is at BTNet end; forwards to BTNet
... etc

However as has been said before, you should get BTNet to resolve this with you directly, rather than adjusting your config. Any future fault resolution could be delayed if the way they've configured the link doesn't actually match with either the NOC handover documentation or their standard practice. Better to resolve it now IMO.

Yes, 100% agree. I done all the traceroutes that I can and it isn't making sense.

The issue I currently have is speaking to someone at BT that knows what they are talking about.....and they dont open until 9.

P.S> ADVA is still amber on the network side, so still something not right.

In reply to a post by tdw42:

The interface specifications are detailed in SIN360 and SIN492. Until recently the handover from the Openreach NTE was optical only, either 1000Base-SX or 1000Base-LX depending on what was ordered, with the demarcation point being the duplex LC connector - they may not take kindly to their SFP being replaced.

I've not ordered an EAD circuit recently so I don't know if the NTE will switch between SFP and 1000Base-T automatically, or if the copper interface has to be specified in the order.

The latter - but they don't like doing it (for good reason)

I’d say you still have a layer 2 issue or incomplete build. Hence that Network LED remaining amber. You won’t succeed until that’s at least solid (if not blinking) green.

Surely if you change the SFP in the access side from MM to SM then it will still work?

I cant confirm 100% that it works yet, as I'm still waiting for the network side to go green.

I have had leased lines delivered from TTB before that were specified as MM and would ONLY work with MM, even with changing the SFP it just refused to work with a DAC or SM SFP module

Perhaps TTB vendor locked the SFP slot.

BTnet don't.....thankfully

Alan - Did you get any joy today with BTNet? This doesn’t read particularly well for them. A bit more urgency wouldn’t go astray.

I was pretty impressed with Focus Group / Virtual1 / Openreach on my recent install. They bent over backwards to help. I even had night-shift cabling crews call in to finish the service internally. Had I not had the internal cabling issue, I would’ve been running within about 5 weeks of order with Xmas / New Year and Covid thrown in between.

My commish call with Virtual1 was booked a few days after Openreach had the circuit in. So far so good. Will be interesting to see how efficient accounts are dnd when something inevitably breaks.

Unfortunately not....I managed to speak to someone, and all they could tell me was the “data build” is not yet complete. I tried to get my point across that my WAN IP was pinging on the internet when it isn’t even plugged in (so clearly not my equipment) but I get the feeling it went straight over. She mainly just kept repeating the build is not complete.

I guess I’ll be waiting a while yet.....

So it turns out, I was given incorrect IP information for my end.

The .10 was indeed the BT end, hence why it is pinging, and my end is .11

It took a lot of effort on the phone to get this one sorted out, but in the end it was the fact that my static IP block is routed to .11, means that .11 is my end, and not BT.

So I have reversed the IPs again on my router.

However, apparently the work they did the other day, created another "fault" at the exchange, which is why I still don't have a green LED on the network side of the ADVA.

I have been told this is being worked on today, and "hopefully" should be completed by 5PM tonight.........joy of joys......

Not a good week. Still down. This problem in the exchange (whatever it is) is still present. Over 2 weeks since the fit and test!

Ive had it escalated twice, and this is from a company with a 5 hour SLA fix time. Obviously doesn’t apply to commissions.

Wish I’d went with Zen or someone.

[censored]. No fear they will sort it. Eventually. Backup connection is it not - slightly less hot hopefully.

If it’s any minor consolation I chose a dud previously. They ducked me about for 6 months before I had enough of their BS. These guys were brilliant though.

I’m sure they will....eventually.

It is a backup yes, but my Virgin leased line has been doing interesting things lately, so will feel much happier whence the BT is up.

What’s interesting is.....if you reboot the ADVA, both network and access LEDs are green and flashing and then after about 10 seconds the network LED goes amber.

I won’t pester about the VM LL foibles. Judging your and my experience, I expect ADVA LED sequences have a mind all of of their own.🎄😎

A rocket to the account manager on Monday!? 🤔

Best wishes next week in any event.

Just come in to work this morning, and both my Access and Network LED's are green!!!

Looks like we were vindicated on the DAC's working in the ADVA after all. Apologies I never fully tested that here. Have tried to keep the setup running steady since go live. There's little point changing here anyhow now.

The next thing to get running here is guess what....backup circuit! 😂

LOL, now you know who NOT to choose

Thanks for all your help in this thread, it was really helpful.

Haha! no problem, glad to be of some help.

Fingers crossed here for the backup circuit - its Virgin!!!! They have to do civils on the footpath on Wednesday (long and painful story involving Cadent breaking new ducts and swept tees). No doubt with my luck, they will put a spade through the new Openreach fibre!

Hi,

I have a 1G/1G Daisy leased line with a Virgin tail, with an Adva OS6250-8M and Cisco C1111-8P managed router connected to my UDM Pro. It's been up and running fine for nearly two years using IPv4, but I need to use IPv6 for some Terragraph kit. I've had the static IPv6 configured by Daisy and can use this successfully with my laptop connected directly to the Cisco, however I can't make it work properly on the UDMP, it can ping6 out fine with SSH on the UDMP and my clients receive an IPv6 address but have no IPv6 connectivity.

I've had had extensive support from Ubiquiti and Daisy, Ubiquiti say that my ISP must support prefix delegation and Daisy are unable to provide it.

Has anyone managed to get this to work?

I do have an Edgerouter 12P and a Mikotik Hex S I can use but are no expert at setting those up.

Thanks for any help!

Hi - First off, your question might get better visibility and answers if you start a fresh thread.

Secondly I’m no expert when it comes to IPv6, but could you not ask Daisy for a /48 or /56 prefix and simply use static addressing in lieu of PD?

https://help.ui.com/hc/en-us/articles/115005868927-U...

Good advice, I will start a fresh thread.

Daisy has already given me static addressing, it's the UDM pro that won't work with it.

I find it hard to believe that the UDMP has this limitation when the help article you linked says:

"Depending on the configuration of the ISP, the UDM/USG can either use DHCPv6-PD (Prefix Delegation) or Static IPv6 addresses to provide IPv6 connectivity to the clients on the LAN. In both setups, the information regarding the connection type and its values is provided by the ISP."

I've studied it in fine detail. Daisy sent me the addresses which should work, just like the examples in the help article.

Hey, sorry to drag up your old post! I noticed you also have a wired only Bt Net connection, can I ask, from your NTe to your router what config did you have to do on your router to get a connection? Static IP, Vlans etc? We’re in the final stages of setup I’m just trying to plan and work out what I’m going to have to do!

Hey, did you get your UDM pro sorted in the end?

Only just seen this post....lol...probably way too late.

So much has changed since I last posted. My virgin leased line has been *upgraded* so I now have 2G on a 10G bearer, and I currently have OpenReach in today splicing in a new 10G bearer, to replace my current 1G/1G bearer.

Judging by the amount of swearing it's not going brilliant

I ended up using some R86S routers from AliExpress, as they are perfectly capabale of doing 10G routing, and put my UDM downstream of that using a slice of my allocated /29.

Router config was easy.....just setting the transit IPs on the WAN, and then splitting out my /29 on my LAN. No VLANS required for BTnet or Virgin Leased Lines.

Anyway, as I say probably a bit late for you, now to figure out why I wasnt notified of a reply on the post......
