I cannot get my OSPF routes to show up in my Linux Routing table. I have tried multiple configurations, but the routes never populate into Linux. They are present in the Bird Interface, but not outside of Bird. I'm sorry for asking a super easy question here, but I cannot find any good basic information on OSPF configurations online.
Default route failed to export, because there is already static default route in kernel. BIRD does not overwrite existing routes in kernel. You should use 'metric 32' kernel protocol option to avoid collisions (or use BIRD 2.0, where this is default). That allows routes to be exported to kernel without error, but the existing routes would still have higher priority.
Here is my BIRDC output:
bird> show route 0.0.0.0/0 via 192.168.100.3 on eth0 [ospf1 16:05:29] !
