int s0.123 point-to-point with int s0.123 multipoint
on router 1.

Subject: OSPF Network type issue (neighboring and not updating)
Hi all,
I am wondering why ospf routering are forming adjacency, but not routing.
Here is the layout;
R3
/ \
r2 r1
It is a hub-spoke topology.
What I am seeing is that r3 is forming adjacency with r2 and r1;
However, r3 can't ping r1's loopback interface.
R3;
interface Serial0/0.123 multipoint
ip address 150.50.123.3 255.255.255.0
frame-relay map ip 150.50.123.1 301 broadcast
frame-relay map ip 150.50.123.2 302 broadcast
frame-relay map ip 150.50.123.3 301 broadcast
no frame-relay inverse-arp

==========================================
If I changed the network type to;
R3:point to multipoint
R2:point to multipoint
R3:point to multipoint ( or ip os hello 30 ),
Then, it would work. I tried and worked.
I guess it comes down to the ospf network type issue.
Can someone explain why neighboring is forming, but not route-updating is
not taking place?
Thanks,
JP
