Michael,
        Can you ping the spokes from the hub? The reason I ask is
because R8 is in OSPF init state. This means that R8 is seeing the OSPF
hellos from R6 but it is not seeing its own router ID in the hellos from
R6. This sometimes indicates a fundamental Frame Relay problem.

Subject: OSPF Non-broadcast network type

Hi,
 
I have a hub-spoke frame relay cloud, the hub (R6) is multipoint
subinterface, spokes (R7, R8) are physical interface. The OSPF network
type is Non-broadcast. I have put neigh statements on hub router R6,
and put ip ospf priority 0 on each spoke router frame interface. But R6
still can not form neighbor relationship with R8. Am I missing some
config here?
