After having been down for some time, I decided to bring up an old test session (IPv6 full table). However, the session doesn't come up fully. I do see a fair amount of UPDATE packets coming in, but then at a certain point the connection gets closed and the routes purged again. All I can find in the logs is "Optional attribute error", even with "debug all all". Is there some other trick to find out what the actual problem is with this session?
Could you send the exact error message and the BIRD version?
Exact error message:
03-05-2011 10:49:22 <RMT> bgp1: Error: Optional attribute error
There are (AFAIK) only two things that may generate such error - malformed NLRI or its next hop attribute. Also NLRI of unexpected kind (like IPv4 in bird6). Perhaps the other side sends both IPv4 and IPv6 in one session? So probably the only thing how to find out the problem is to get dump of BGP traffic using tcpdump (like tcpdump -n -s 0 -w file ...) and examine that or send it to me. -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
