The default behavior for a interface in a bridge-group is to bridge all
protocols...Thus, if you are using IRB to bridge IP between two interfaces
and route to a third, but you are also running IPX on all three interfaces
(using 3 different network numbers) and you only want to ROUTE the IPX
traffic, you need to tell the router not to bridge the IPX trafiic...For
example:
interface fastethernet 0/0
bridge-group 1
ipx network 1
interface fastethernet 0/1
bridge-group 1
ipx network 2
interface fastethernet 0/2
ip address 10.1.1.2 255.255.255.0
ipx network 3
interface bvi 1
ip address 10.1.1.1 255.255.255.0
The above configuration would cause the router to try to bridge IPX from
f0/0 to f0/1, so this config would also need:
bridge 1 route ipx
no bridge 1 bridge ipx
