FreeBSD/zebraOSPF not updating routingtables
Perjan Moors
something, but can't figure out what it is.
I have no practical experience in OSPF, just theoretical
I have no experience in FreeBSD, just Linux and solaris.
I am not using IPv6, at least not conciously...
The folowing is my situation, consisting of 4 machines:
Internet

+-----------------+
matrix is a windows 2000 professional PC, routing traffic towards the
internet
vondel and Patten are FreeBSD machines, running Zebra OSPFd
linde is a windows 98 machine for testing purposes
All directly connected addresses can be pinged
linde can ping matrix
Both routers find neigboring interfaces, but no routing tables are updated.
That is:
- I cannot ping the dummy address of vondel from patten and v.v. (I even
cannot ping the dummy addres of patten from patten)
- when I disconnect the cable from 10.1.0.1, linde cannot ping 10.1.0.2
anymore, while a route still exists
What am I overlooking???? Please help!
what do link#1-link#4 in the routingtables mean?
Àll relevant configs I can think of can be found below.
Regards,
Perjan
