OSPF Single Area on Frame Relay network

hi I just configure this network

R3--R1--R4

and these are the conf

hostname R3 ! interface Serial0 ip address 10.1.1.3 255.255.255.0 encapsulation frame-relay ip ospf network non-broadcast ip ospf priority 0 ! router ospf 1 log-adjacency-changes network 10.1.1.0 0.0.0.255 area 0

hostname R1 ! interface Serial0 ip address 10.1.1.1 255.255.255.0 encapsulation frame-relay ip ospf network non-broadcast ip ospf priority 1 ! router ospf 1 log-adjacency-changes network 10.1.1.0 0.0.0.255 area 0

hostname R4 ! interface Serial0 ip address 10.1.1.4 255.255.255.0 encapsulation frame-relay ip ospf network non-broadcast ip ospf priority 0 ! router ospf 1 log-adjacency-changes network 10.1.1.0 0.0.0.255 area 0

Result R3 can ping R1 but not to R4 and vice versa. R1 can ping anywhere.

I know that I should use ptp or ptm, I just want to see how it works using non-broadcast mode with 'ip ospf priority' command.

If it won't work, why? If it works, how and why?

Hi,

AFAIK in nonbroadcast mode neighbors must be statically configured. R3--R1--R4

So on R1 router (DR) you need to specify neighbors.

- neighbor 10.1.1.3 priority 0

- neighbor 10.1.1.4 priority 0 in (config-router) mode.

I think that your configuration with 'ip ospf priority x' should work in broadcast mode (but I haven't tried that)

Off course you need 'full mesh' to use broadcast mode.
