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.
