Configuring Transparent Bridging

Transparent and SRT Bridging Configuration Examples

Note To get spanning-tree information by bridge group, use the show span command. Included in this information is the root bridge of the spanning tree. The root bridge for each spanning tree can be any router in the spanning tree.

The routers in this network are configured for bridging and demonstrate some of the bridging features available.

Configuration for Router A

Router A demonstrates multiple bridge groups in one router for bridged traffic separation.

In Router A, the Token Ring interfaces are bridged together entirely independently of the other bridged interfaces in the router and belong to bridge group 1. Bridge group 1 does not use a bridge domain because the interfaces are bridged independently of other bridged subnetworks in the network topology and it has no connection to the FDDI backbone.

Also in Router A, the Ethernet interfaces belong to bridge group 3. Bridge group 3 has a connection to the FDDI backbone and has a domain defined for it so that it can ignore BPDUs for other bridged subnetworks.
