Description

The Bridge-Group Virtual Interface (BVI) becomes available on routers when the bridge irb command has been given. This interface allows the router to route and bridge the same protocol over the same interface. The bridge group-number must match the bridge group defined for the bridge.

Example

In this configuration, serial0 and serial1 are bridged, and traffic is routed through those interfaces out through ethernet0:

bridge irb
bridge 1 protocol ieee
!
interface serial0
 bridge-group 1
!
interface serial
  bridge-group 1
!
interface ethernet 0
  ip address 10.11.1.1 255.255.255.0
!
! Configure the virtual bvi interface with a bridge group number of 1
interface bvi 1
  ip address 10.10.3.1 255.255.255.0
!
! Now configure the routing for the bridge
bridge 1 route ip
