Use the following commands on the remote PE router (PE 2) to configure the VPLS topology shown in Figure 129.
- ! Configure VPLS instance vplsA.
- host2(config)#bridge vplsA vpls transport-virtual-router
default
- !
- ! Configure VPLS instance vplsB.
- host2(config)#bridge vplsB vpls transport-virtual-router
default
- !
- ! Configure Fast Ethernet interface 2/5 between PE 2 and
CE 3,
- ! and assign it to vplsA as a trunk interface.
- host2(config)#interface fastEthernet 2/5
- host2(config-if)#bridge-group vplsA subscriber-trunk
- host2(config-if)#exit
- !
- ! Configure bridged Ethernet interface 6/0.21 between PE
2 and CE 4,
- ! and assign it to vplsB as a trunk interface.

the loopback interface.
- host2(config)#ip router-id 2.2.2.2
- !
- ! Configure ATM core-facing interface 6/1.20 between PE
2 and the P router,
- ! and assign it an IP address.

interface.
- host2(config-subif)#mpls
