A bridge will not send a data back out the interface it was received on. You
need to use point-to-point subinterfaces to bridge across a frame hub.

Subject: Bridging over FR hub and spoke
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
configuration. 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 only 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.
The result:
>From R1 -PASSED
>From R2 -FAILED (even after "clear arp")
Has this got something to do with split-horizon?
Thanks in advance
David
