I've got this in my bird.log, after this bird has crashed... Bird is 1.0.7. And this is my OSPF config:

protocol ospf ONNET_BB { export none; import filter { if ospf_metric2 = 65535 then { reject; } accept; }; area 0.0.0.0 { interface "eth0" { hello 15; cost 11; priority 7; dead count 4; retransmit 7; }; }; }

I think this all happened because off one Cisco router that can't become ospf neighbour with bird, although it neighbours with other Cisco's just fine.

This could be a bug in bird. Could you send me 'ip route list' and 'ip addr list' and (maybe) tcpdump of hello packets from the cisco? Ondrej Filip
