If you have 3 routers configured for FR and transparent bridging, with
the central router a multipoint interface and the end routers plain
serial interfaces, does the central router have to be the root bridge?
I cannot get it to work unless this is the case. If the central
routers is not given a lower bridge priority then each of the end
routers think that they are the root.
1 end router:
interface Serial0
ip address 150.50.24.4 255.255.255.0
encapsulation frame-relay
no ip route-cache
no ip mroute-cache
frame-relay map bridge 401 broadcast
bridge-group 1
end
Central router:
interface Serial0.247 multipoint
no ip route-cache
frame-relay map bridge 107 broadcast
frame-relay map bridge 104 broadcast
bridge-group 1
end
2nd end router:
interface Serial0
ip address 150.50.24.7 255.255.255.0
encapsulation frame-relay
no ip route-cache
no ip mroute-cache
frame-relay map bridge 701 broadcast
bridge-group 1
end
Thanks,
Gerry
