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?
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" {
};
};
}
bird> show ospf neighbors
