Hi group,

        I am having some difficulties with the following bridging scenario:

        e0-R2-s0------------FR CLOUD---------s0-R3-BVI1
                                        |
                                        |
                                        |
                                   e0-R1 (HUB)

R1 is the Root Bridge and the hub in this frame-relay hub and spoke configurati
on. All has bridging switched on. Since they are all using physical interface,
I need to configure "frame-relay map bridge [dlci] broadcast" on every router.
The R1 will have two frame-map bridge mappings as it is the hub. I also enabled
 IRB and created a BVI1 on R3. The command "bridge 1 route ip" is configured on
ly on R3 since the BVI is there.

Tested by pinging the BVI1 on R3 from a PC connected to the e0 of R1 and R2. Th
e result:

>From R1 -PASSED
>From R2 -FAILED (even after "clear arp")

Has this got something to do with split-horizon?

Thanks in advance
David
