Hi,
I'm playing with ospf on few Linux hosts pretending to be routers in single LAN.
Unfortunately one host has a problem. bird (1.2.5, git master) thinks route(r)s are "unreachable" (as seen by show ospf state all). It never gets into full state. All other routers have no such problem. There is no firewall here.
Any clues?
I had similar problem but on bird 1.2.1. The problem was created by ip address that was bind to interface. I got two ip's on the interface and bird as a source used second IP.
When I deleted second IP and restared bird everything works correctly.
Can't do that - these IPs are used and needed.
Tou can always check it with tcpdump or wireshark on ospf lan.
tcpdump -vv -nn -i <interface> host 224.0.0.5
I don't see bad IPs used, dump using tcpdump -vv -nn -i eth0 ether host mac-addr and proto 89 at http://carme.pld-linux.org/~arekm/p/ospf.log.gz Sometimes, rarely it seems to be working and kernel table gets all routes but in most cases all routers are "unreachable" as seen by bird. -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/
