Configuration on PE 1 (Local PE Router)
Use the following commands on the local PE router
(PE 1) to configure the VPLS topology shown in Figure 129.
- ! Configure VPLS instance vplsA.
- host1(config)#bridge vplsA vpls transport-virtual-router
default
- !
- ! Configure VPLS instance vplsB.
- host1(config)#bridge vplsB vpls transport-virtual-router
default
- !
- ! Configure Fast Ethernet interface 2/1 between PE 1 and
CE 1,
- ! and assign it to vplsA as a trunk interface.
- host1(config)#interface fastEthernet 2/1
- host1(config-if)#bridge-group vplsA subscriber-trunk
- host1(config-if)#exit
- !
- ! Configure bridged Ethernet interface 6/0.12 between PE
1 and CE 2,
