Bridging Ethernet Ports of 1841 Router

Hi Everybody.

I am trying to configure Cisco 1841 Router Ethernet ports fa 0/0 & fa 0/1 into a single bundle similar to Teaming which is done in Servers.

So that we can configure one IP address for both the ethernet ports and connect two cables for redundancy.

Is it possible to achieve this design? Kindly help

Hello R. B. Kumar,

you can do this with IRB but only one physical link will be active at any given time.

bridge 1 protocol ieee

bridge 1 route ip

int f0/0

no ip addr

bridge-group 1

int f0/1

no ip addr

bridge-group 1

int BVI1

desc logical L3 interface for bridge-g 1

ip address 10.10.10.1 255.255.255.0

no sh

STP will block one of the two links

Redundancy can be achieved and you can connect the two cables to two different lan switches

Hope to help

Giuseppe
