Example 1: Bridging with Bridged Ethernet

Copyright © 2010, Juniper Networks, Inc.
Use the no version to disable routing of the specified protocol in the specified bridge
group.
See bridge route.
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.
The following example illustrates how to configure transparent bridging with bridged
Ethernet.
Create the bridge group.
1.
host1(config)#bridge westford01
Create an ATM major interface.
2.
host1(config)#interface atm 3/3
Create an ATM 1483 subinterface and associated PVC.
3.
host1(config-if)#interface atm 3/3.1
host1(config-subif)#atm pvc 1 0 10 aal5snap
Specify bridged Ethernet as the encapsulation method on the subinterface. The
4.
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
Create a PPPoE major interface over the bridged Ethernet interface. Because this
5.
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
