What is "openbgp version 3.72"?! I see 3.6, 3.7, 3.9 in the ftp directory, no 3.72. I think it's better to run a normal and supported OpenBSD version if you're using OpenBGP (-current snapshots are probably the best choice at this point in the release cycle). Anything else, you increase the number of things that can go wrong, and what's the point in that? > peer2="192.168.12.130" > myip="192.168.12.129" > network 192.168.12.128/25 Why announce the network to which both hosts are already connected? Try removing that because it's after that route has been added that the problem seems to start... If that's not it, maybe it will help to see some `tcpdump -nvvs5000 port bgp' on the relevant network interface (it should give a good readable decode of the BGP/TCP messages). You might need to change to standard OpenBSD to do that though. I saw something similar (session came up, receive <= 20 prefixes, drop out) recently where a transit-isp-md5-snafu resulted in their session coming from an out-of-subnet address(?!) I kept some traces but that's since fixed and I'm not going to break it again to diagnose (-:
