Hi Yasser,

I'm not sitting in my Lab right now.

I configured the BRI 0 as being part of ospf area0.
Sh ip route shows the route as connected.. even though R3's loopback and
BRI are in different networks. (That's strange, I have to admit)

Thanks for your comment.

JP

Layer 3 to layer 2 mapping should not create a connected route. Can you
paste your config and routing table?

As Richard suggested, it's more like an ospf route type problem.

Hi Richard,

The problem is the route through the BRI 0 is not seen as OSPF, it's
seen as connected. The administrative distance rules here.

Are both routes Intraarea, Interarea, or one is Intraarea and the other
Interarea ? If they are of the same type, then changing the cost to a
much higher one on the dialer should do the work,

Hi all,

If you conisdere the following layout:

    FR FR

R1-----R2-----R3

 |____________|

        ISDN

We have enabled ospf everywhere on this network, and used a dialer watch
on R1 to "track R3's loopback interface".

The problem is when ISDN comes up, the route to R3's loopback appears
then as connected (there's layer 3 to layer 2 mapping).

Thus, even when the Frame-relay path comes back up, the ISDN line stays
up...

How can I make the route leant through OSPF to be preferred?

Your comments would be much appreciated.

Thanks

Regards,

JP
