Hello,
I have a very simple frame relay/ospf question. For some reason, I
can't make this work ...
I have a hub router (r1) and two spoke routers (r2 & r3). r1 has a
multipoint sub-interface and r2 & r3 are using physical FR interfaces.
They are all in the same ip subnet which is in OSPF Area 0.
On r1: there are 2 frame-relay map statements pointing to r2 and r3, it is
configured as an "ip ospf netw point-multipoint".
On r2 &r3 each : there is a single frame-relay map statement pointing to r1
and the interface is also configured as "ip ospf netw point-multipoint".
The problem is with OSPF adjacency - r1 has both r2 & r3 as neighbors with
a state of FULL. r2 & r3 have r1 as their neighbor with a state of full
BUT they also have each other as neighbors and they are in an EXSTART
state.
My understanding is that the two spoke routers should only form an
adjacency with the hub in this point-to-multipoint configuration. r2 and
r3 should not even try to become neighbors (?). I am working with a
full-mesh frame relay network but inverse-arp is disabled (by virtue of the
map statements and manually typing 'no frame-relay inverse-arp' at the
interfaces).
Can anyone provide any suggestions? Thanks for your help.
p.s. I have serached the archives but wasn't able to find an answer to this
particular problem.
