[AusNOG] Superloop Connect LNS config

Fri Dec 10 19:02:19 AEDT 2021

“I couldn’t even ping any LAC addresses with the source IP of my BGP interface”.

Okay that says a lot and if you’re not getting ICMP responses, I’d say the LAC’s can’t reach your LNS’s loopback which is either going to be a BGP advertisement issue from your end ‘Check your loop is visible in as show ip bgp neighbor x.x.x advertised-routes’ and then if it is, absolutely open a case with SLC for them to check that they’re accepting it and distributing it to there LAC’s.

Hey Nathan,

Unfortunately not seeing any attempts. Possible that my CPE is an issue as I pre-configured it and left in plugged in at home this morning on a spare UNI-D port, am about to head home to check that. I haven’t setup a capture yet but I did setup an ACL and can’t see ANY traffic counters incrementing for anything coming from Superloop’s LAC range (unless I do a ping). Good to hear though that it’s meant to be identical. I just hope I’ve done something, otherwise I’ll be waiting till Monday! Argh.

I’ve done an identical config to what I have for NWB. The only difference now is I specified a source-ip of one of the assigned loopback addresses, as Superloop’s LACs seem to be a bit more strict about that – I couldn’t even ping any LAC addresses with the source IP of my BGP interface – had to be the loopback. Source-ip is the only way I found to specify a source address for the L2TP traffic – but I might be wrong?

Hi Rhys,

Are you seeing any L2TP tunnels trying to establish, if your moving from NWB the VPDN configuration should literally be identical once you put in the local address and secrets etc.

Hi Everyone,

Happy Friday.

Just wondering – can anyone help with an example LNS config for Superloop Connect NBN perhaps? Have been provisioned in the last few days and trying to get a test service online today so that we are OK to get services online next week.

Been waiting to hear back from the network team most of the day but I think at this point I’m not likely to hear back till Monday, so if anyone has anything handy so I might be able to try and get things online over the weekend it’d be appreciated. We’re on AAPT NWB at the moment and I’ve done basically the same config.

Unfortunately though I have BGP sessions up and can ping the LACs from the designated loopbacks, I’m not seeing any dial-in attempts to establish a tunnel from any of the LACs, or anything in my L2TP debugs. I do have a CPE connected to a test service. I am hoping it’s my end and not theirs!

Thanks all.
