SO the solution is to do point-to=point subinterfaces on the
hub router (c2651).
interface Serial0/0.1 point-to-point
frame-relay interface-dlci 101
bridge-group 1
!
interface Serial0/0.2 point-to-point
frame-relay interface-dlci 102
bridge-group 1
I think the issue why this setup will not work with a multipoint
on c2651, is that it will get a bridge update from c5301 and then
try to flood out to all other bridges. But c2651 will not flood back
out the interface it just got the update from. Almost like split-horizon.
So the way around this is to create two subinterfaces. Then if a flood
comes from one of the bridges it will also be forwarded to the other spoke.
