Just for S's and G's, try removing the "ospf network non-broadcast" command
or add a neighbor command to your OSPF. If I remember correctly, using this
type of OSPF network requires you to explicitly list your neighbors.

Subject: OSPF Neighbor over ISDN
I am not able to get 2 routers to form an OSPF neighbor relationship over an
ISDN Line. In the past this has always worked. When the ISDN line comes us
the two routers form a neighbor relationship with the dead timer going to
null. I am able to ping across the link and a "Show ip ospf neigh" command
verifies that each neighbor sees int BRI 0 in area 10. Debug ip ospf neigh
and ospf lsa indicates that neither hello packets are not being received
over the isdn line.
Any ideas?
Thank you
Elton
