no idea if it fits your situation but an interesting thing happened to me in
the lab a few days ago..........
same problem - adjacency wouldn't form.
once debug ip ospf adjacency was turned on it told me that the MTU didn't
match.
I was going over a bridged emulated lan service (atm and ethernet)
terminating on a BVI.
The BVI had a MTU of 4460 (default for ATM?)
once I changed it to 1500 the adjacency formed immediately and I had OSPF
routes at the distant end.
great learning exercise with debug.
