Michal Thank you very much, the second set of commands worked, route = delete and then ifconfig on the interface, is anyone have any idea on = fixing this? why FreeBSD is preferring the OSPF route instead of connected one?

I think, that it will be = type UG1, because quagga installed it when the interface was down (ospfd = deamon received it over another link). >> Anyone has any idea on this issue? i have searched the internet and = some people seem to have the same problem all with FreeBSD, Linux = version dosnt have this problem, some of them speaking for a patch = floating arround, but i didnt find any information on it >> i have changed the version of quagga from 0.9.15 to 0.9.16 but not = solved, i have compiled the quagga with TCP SOCKETS support but again = the problem dosnt solve, the only workaround is to reboot the whole = machine >> even if i restart quagga it doesnt work. >> =20 > Workaround is to add route manually, like this: >=20 > route delete 10.10.32.32/30; route add 10.10.32.32/30 -iface em0 > or > route delete 10.10.32.32/30; ifconfig em0 10.10.32.34/30 >=20 > I think freebsd kernel could install "connected" route when interface = goas up (and replace UG1 route) because connected could be preferred = over dynamic route. So this seems like FreeBSD bug , instead of quagga = ones. >=20 > Michal
