Bridging two FastEthernet

[d.bigerstaff]

I have a 2811 router with Software Version 12.3(11)T10 / CME 3.2 and i'm looking to make a bridge between fa0/1 and fa0/0. I've been looking into the bridge-group commands in the online documents and havent managed to figure it out yet.

If anyone could give me a quick push in the right direction i'd much appreciate it.

thanks.

Check below for the bridge configuration. However, please beware that if you enable IP routing, the IP traffic will not be bridged.

Hope this helps.

The solutions so far have been to disable routing, but you can bridge the interfaces and still route. The method is:

bridge irb

bridge 1 ieee

bridge 1 route ip

int fa0/0

no ip address

bridge-group 1

int fa0/1

no ip address

bridge-group 1

int bvi1

ip address x.x.x.x m.m.m.m

This will place both physical interfaces into the bridge and the router will have the address and mask defined in bvi1 on that bridge.

Hope that helps...
