Brian,

I know that your way works.
However, what I am trying is to combine with DLSW lite encap.
So, I had to try this way.

R2;
dlsw local-peer peer-id 192.168.2.2
dlsw remote-peer 0 frame-relay interface Serial0/0 201
dlsw bridge-group 1

interface Serial0/0
 ip address 172.16.123.2 255.255.255.0
 encapsulation frame-relay
 frame-relay map llc2 201 broadcast

R1;
dlsw local-peer peer-id 172.16.10.1
dlsw remote-peer 0 frame-relay interface Serial0/0.123 102
dlsw bridge-group 1
interface Serial0/0.123 multipoint
 ip address 172.16.123.1 255.255.255.0
 frame-relay map llc2 102 broadcast

Shouldn't this work?

Your Frame-relay mappings do not look incorrect. Can you ping from R1 to
R2?

If not try this:

R2;
interface Serial0/0
 ip address 172.16.123.2 255.255.255.0
 encapsulation frame-relay
 frame-relay map ip 172.16.123.1 201 broadcast

R1;
interface Serial0/0.123 multipoint
 ip address 172.16.123.1 255.255.255.0
 frame-relay map ip 172.16.123.2 102 broadcast

I am still not getting ospf neighbor up.
Interestingly, I get the DLSW peering up.

On R2 you do not have the broadcast keyword on the Frame-relay map
statements. Init state means you are receiving hellos from the remote
end but you are not seeing your own router ID in the hellos.

Also there is no need for the "ip ospf priority 0" command with a
point-to-multipoint OSPF network.

Hi all.
Here is the problem I have.
 
R2(spoke)-----------R1(Hub)
 
They are running ospf.
I don't get the neighboring between these two routers.
It is stuck in INIT stage.
 
R2;
interface Serial0/0
 backup delay 0 10
 backup interface BRI0/0
 ip address 172.16.123.2 255.255.255.0
 encapsulation frame-relay
 ip ospf message-digest-key 1 md5 cisco
 ip ospf network point-to-multipoint
 ip ospf priority 0
 no fair-queue
 frame-relay map llc2 201 broadcast
 frame-relay map ip 172.16.123.2 201
 frame-relay map ip 172.16.123.3 201
 no frame-relay inverse-arp
 
R1:
interface Serial0/0.123 multipoint
 ip address 172.16.123.1 255.255.255.0
 ip ospf message-digest-key 1 md5 cisco
 ip ospf network point-to-multipoint
 frame-relay map llc2 102 broadcast
 frame-relay map ip 172.16.123.1 102 broadcast
 frame-relay map ip 172.16.123.3 103 broadcast
 no frame-relay inverse-arp
 
r2#sh ip ospf nei
 
Neighbor ID Pri State Dead Time Address
192.168.1.1 1 INIT/ - 00:01:35 172.16.123.1
r2#
 
If you need more configs, let me know.
 
Any idea why this fails with the neighboring?
 
Thanks
 
JP
