Hi Group,
I have a FR setup with 3 routers, R1, R2 and R3 in fully meshed network. The FR link is setup
using following conditions.
--------------
On R1: Peer with R2 using static map + Peer with R3 using inverse-map
On R2: Peer with R1 and R3 using static maps.
On R3: Peer with R1 and R2 using static maps.
Do not use any sub interfaces on any router. Run OSPF Area-0 over Frame-relay all the routers.
--------------
I configured the following and I'm seeing that OSPF peering between R1 and R2 reaches till
EXCHANGE state but because of continuous retransmissions it fails and neighborship goes down.
Tried resetting the ospf processes, shutting down the serial i/fs etc.. but didn't work. Has
anybody hit the same problem before ?
