Configuration Examples
This section provides examples that show how to configure transparent bridging on
the router. With each step, an illustration shows how the router is building the
interface column.
Example 1: Bridging with Bridged Ethernet
The following example illustrates how to configure transparent bridging with bridged
Ethernet.
1.
Create the bridge group.
host1(config)# bridge westford01
2.
Create an ATM major interface.
host1(config)# interface atm 3/3
3.
Create an ATM 1483 subinterface and associated PVC.
host1(config-if)# interface atm 3/3.1
host1(config-subif)# atm pvc 1 0 10 aal5snap
4.
Specify bridged Ethernet as the encapsulation method on the subinterface. The
encapsulation keyword implies that the bridged Ethernet interface is the only
interface stacked directly above the ATM 1483 subinterface. As a result, the
bridged Ethernet interface cannot have a peer interface stacked above the same
lower-layer interface.
host1(config-subif)# encapsulation bridge1483
5.
Create a PPPoE major interface over the bridged Ethernet interface. Because this
command does not use the
encapsulation keyword, the PPPoE interface can
have one or more peer interfaces stacked above the same bridged Ethernet
interface.
host1(config-subif)# pppoe
