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.
Tou can always check it with tcpdump or wireshark on ospf lan.
tcpdump -vv -nn -i <interface> host 224.0.0.5
ps. is there bird related irc channel or do devs use irc? (arekm@freenode)
config is:
protocol ospf MyOSPF {
debug all;
rfc1583compat;
import filter from_bgp;
export none;
area 0.0.0.0 {
networks {
x.x.x.0/22;
};
interface "eth0" {
};
};
}
