Re: [AFMUG] ASN check
Its because we have upstreams in different towns both doing BGP. If the path on our network between them goes down it orphans customers so this allows a hobbled failover. We have passed 3-400mbps across it to our surprise. I think our upstreams peer with zayo near each other. We originally had EOIP but it was problematic and unreliable On Tue, Apr 23, 2024 at 3:08 AM TJ Trout wrote: > Why gre?

Yeah, apparently they moved our BGP to a new switch and had a syntax error. We never noticed because our backup external GRE flowed bypass traffic. I assume enough was getting out to wherever our upstreams meet there was announcement.

Re: [AFMUG] ASN check
We had a provider maintenance on the 12th and never realized all the bandwidth moved to the other peer. though its odd, the two locations have an external GRE tunnel that is up, so some prefix propagation has to be occurring somewhere. I restarted and cleared the BGP session, had only been up since the 12th now.

Re: [AFMUG] ASN check
Well this CIRBN LLC is peered with you I don’t know who your other peer is supposed to be, but I’d make sure your BGP connection to them is in the “Established” state and maybe reset that connection. “clear ip bgp neighbor x.x.x.x” or whatever equivalent command on your router. Also verify you’re advertising some routes to the other guy. If you’re connected and advertising routes to him then quite possibly he’s not redistributing them. Lumen does that to us on a semi-regular basis, so we have to watch for that now. -Adam From: AF On Behalf Of Steve Jones Sent: Tuesday, April 16, 2024 3:26 PM To: AnimalFarm Microwave Users Group Subject: Re: [AFMUG] ASN check So I am reading that right, my peer is up to me but not announcing me On Tue, Apr 16, 2024 at 2:11 PM Josh Baird mailto:joshba...@gmail.com> > wrote: https://bgp.he.net/AS40121#_peers On Tue, Apr 16, 2024 at 3:09 PM Steve Jones mailto:thatoneguyst...@gmail.com> > wrote: 40121 can somebody else verify this is only showing one peer, im no looking glass master, but it appears one of our peers stopped announcing on the 12th -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
