IP Bridging



In this scenario two hosts belong to the same IP subnet but are assigned to 2 seperate VLANS: vlan 16 and vlan 36. I implement IP bridging to enable connectivity between the hosts.

On R6 I configure the following:-

1) configure the bridge group and enable ip routing

bridge 1 protocol ieee
bridge 1 route ip

2) assign the interfaces to the bridge group

config-if# bridge group 1

3) enable Intergrated Routing and Bridging (IRB)
bridge irb

4) create the bridge virtual interface and assign an ip address
#int bvi 1
config-if# ip address 136.1.136.6 255.255.255.0

I can now ping 136.1.136.1,136.1.136.3 and 136.1.136.6 from all routers.
