You might want to add "ip ospf network point-to-multi" thro'out your frame
relay cloud so that they can form the adj
for ex there is no ip ospf network command in the following config.
interface Serial0.1 multipoint
ip address 10.10.1.1 255.255.0.0
frame-relay map ip 10.10.1.3 103 broadcast
frame-relay map ip 10.10.1.5 105 broadcast

Hello Group,
I think in my config I have run into some issue with NBMA and OSPF
because I can not exchange any routes even though I have full adjacency
established.
What is wrong?
