Hello,

I'm rather confused by this problem as I have a very simple
configuration. I have a linux router talking to a Cisco 3550 and it
seems to not seeall the routes.

Here's my configuration, if it was default I didn't paste it. Its very simple.

Quagga config:

router ospf
 redistribute kernel
 redistribute connected
 redistribute static
 network 192.168.1.0/30 area 0.0.0.0

Cisco config(I wr e'd the Cisco, the only other non default config is
an ip address):
router ospf 1
 log-adjacency-changes
 network 192.168.1.0 0.0.0.3 area 0.0.0.0


Connected routes according to Zebra:
C>* 66.103.230.0/24 is directly connected, eth0
C>* 66.103.254.0/24 is directly connected, eth0
C>* 69.39.67.0/24 is directly connected, eth0
C>* 69.39.86.0/24 is directly connected, eth0
C>* 69.39.88.0/24 is directly connected, eth0
C>* 69.39.89.0/24 is directly connected, eth0
C>* 74.126.13.0/24 is directly connected, eth0
C>* 74.126.18.0/24 is directly connected, eth0
C>* 74.126.19.0/24 is directly connected, eth0
C>* 209.124.50.0/24 is directly connected, eth0
C>* 216.234.124.0/24 is directly connected, eth0

66.103.230.0/24 is missing from the routes. It is setup the EXACT same
as all the other networks on the Linux box. The Cisco is even saying
it received 2 subnets for 66.0.0.0/24. I'm almost leaning towards
hitting a Cisco bug as I've not had much trouble with quagga at all.
Just wanted to see if anyone else has seen this type of behavior.

Thanks,
