Hi,

Bridge-group is used to bridge interfaces rather than routing between them on a Cisco router, for example to bridge 2 Ethernet interfaces:

Router#configure terminal

Router(config)#bridge 1 protocol ieee

Router(config)#interface ethernet 0

Router(config-if)#bridge group 1

Router(config-if)#no shut

Router(config)#interface ethernet 1

Router(config-if)#bridge group 1

Router(config-if)#no shut

Router(config-if)#end

1.You can configure up to eight bridge groups of two interfaces each.

2.You can only assign two interfaces to a bridge group.

3.You cannot assign the same interface to more than one bridge group. Each bridge group connects to a separate network.

4.Bridge group traffic is isolated from other bridge groups; traffic is not routed to another bridge group unless using BVI (Bridge Virtual Interface) interfaces and IRB (Integrated Routing and Bridging).

HTH, please do rate all helpful replies,

Mohammed Mahmoud.

Hi,

A bridge group is configured on a router in order to bridge between interfaces rather than to route. The interfaces of this group bridge between themselves.

Bridging between the interfaces of a router is required when a vlan has to span accross a router.

HTH, Please rate if it does
