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
