Hi,
You can also do a "show ip ospf database router <neighbor_id>" to see what lin
ks are being originated by the router in your Area 0 domain. If you do a "show
ip ospf database" you will not see links that have been originated in that same
area. If you are thinking about Network Summary Links (LSA Type3) those LSAs w
ill only be used when routes are being advertised by a different area. Let's sa
y you have another area, area 2. The ABR that connects Area 0 and Area 2 will o
riginate Type 3 LSAs advertising the routes that are within area 2 to your bac
kbone area 0 and vice versa.
Here is a great link from Cisco http://www.cisco.com/warp/public/104/ospfdb6.ht
ml . I also did a example for sh ip ospf database router
HTH,

Mike,
You haven't given us enough information to help. Try a
show ip ospf interface to see if those interfaces are
running OSPF in the first place. Check your network
statements under the OSPF process. I suspect they do
not enable OSPF on the interfaces you speak of. Hope
that helps.
