On R1 and R3 map ip address of each other to the same dlci
Configure on interfaces (R1, R2 and R3) ip ospf net p2m

Objet : OSPF over Frame Relay

Hi All

Got a problem with OSPF over FR.

r1--------r2--------r3

r2 to use a multipoint subinterface, others to use phyiscal interface.
All are in the same subnet.
One dlci to each router r1 to/from r2 122/221, r2 to/from r3 223/322.

What is the best way of approaching this problem.

Have configured frame network and all dlci's are active.
Have configured the interfaces as network type broadcast and got partial
success - not all routes were exchanged- between r3 and r2 but nothing
between r1 and r2.
Tried using non-brd on r1 and r3 and point-to-multi non-brd on r2 and
neighbours in OSPF, got neighbours up but no routes at all.
Tried using non-brd and neighbours in OSPF, got neighbours and some routes -
between r3 and r2 but nothing between r1 and r2.

Configs for last attempt below

!Router r1
interface Serial0
ip address 15.2.34.1 255.255.255.0
encapsulation frame-relay
ip ospf network non-broadcast
frame-relay map ip 15.2.34.2 122 broadcast
no frame-relay inverse-arp
!
router ospf 1
network 15.2.1.1 0.0.0.0 area 0
network 15.2.34.1 0.0.0.0 area 0
neighbor 15.2.34.2 priority 1
!
!Router r2
interface Serial0.1 multipoint
ip address 15.2.34.2 255.255.255.0
ip ospf network non-broadcast
frame-relay map ip 15.2.34.1 221 broadcast
frame-relay map ip 15.2.34.3 223 broadcast
!
router ospf 1
network 15.2.2.2 0.0.0.0 area 0
network 15.2.34.2 0.0.0.0 area 0
neighbor 15.2.34.1 priority 1
neighbor 15.2.34.3 priority 1
!

!Router r3
interface Serial0
ip address 15.2.34.3 255.255.255.0
encapsulation frame-relay
ip ospf network non-broadcast
frame-relay map ip 15.2.34.2 322 broadcast
no frame-relay inverse-arp
!
router ospf 1
network 15.2.3.3 0.0.0.0 area 0
network 15.2.34.3 0.0.0.0 area 0
neighbor 15.2.34.2 priority 1
!

Many thanks
