SV: [nsp] OSPF over RBE - no full adjacency

[jgh_cisco]

Hello !

You have an IP MTU issue.
OSPF checks the MTU before building the adjacency.
ATM defaults to 4470 bytes, and Ethernet 1500.

Try adding "ip mtu 1500" under your ATM subinterface.

You should get a descriptive debug message if you do "debug ip ospf adj"
