Why would there be discrepancies between the ospf database and the entries in the routing table. If I do show ip ospf database there are a significant number of entries that are not shown but are in the network list under router ospf....
Why would this be? We are having occasional connectivity problems with 2 of the subnets that are not in the ospf database but are in the network router list.
Any help you can give is appreciated.

hi Alex,
As I said earlier, all routers with in an area would have the same topology database. That means, same entries.
The only thing i think u are missing is, you have to check it under the Router LSA for the advertising router.
show ip ospf database router <192.168.162.1>
Check the same command on the router in which u suspect its not there.
regards,
Sudeep
