I am having problems getting ospfd to work with 802.1q vlans. I have 2
existing ospfd servers that are working correctly with physical interfaces in
each network they are trying to take part in. I recently built new box that
I'm trying to use vlans as it only has 2 interfaces and I want it to talk to
3 different networks. When I start `ospfd -d` to see why no networks ever
get populated into the FIB I get the follow errors. Is there anything I can
do to resolve this problem?
