Dear All,

As a new user trying to implement bird version 1.5 into some lab environment, I’ve made my first easy setup:

Cisco ASR box ( with many VRFs ) ßà FreeBSD with Bird installed ( with many FIBS ). I’m trying to peer one of cisco vrf with one of the fib using OSPFv2.

On Cisco side my config looks like:

interface GigabitEthernet0/0/1/9

description -=- GSS server -=-

mtu 9014

negotiation auto

load-interval 30

interface GigabitEthernet0/0/1/9.1501

description -=- to-testbed-server-radius -=-

mtu 1514

vrf Corp1

ipv4 address 10.98.251.245 255.255.255.252

encapsulation dot1q 1501

router ospf Corp_Clients

vrf Corp1

area 0

interface GigabitEthernet0/0/1/9.1501

mtu-ignore enable

On FreeBSD side my bird.conf contains:

#log syslog { debug, trace, info, remote, warning, error, auth, fatal, bug };

log syslog all;

log stderr all;

#debug protocols all;

timeformat base iso long;

timeformat log iso long;

timeformat route iso long;

log "/var/log/bird.log" all;

log stderr all;
