Configuration on CE1 (Local CE Router)
Use the following commands on the local CE router (CE1) to configure the MPLS L2VPN
tunnel over LAG shown in Figure 123 on page 551.
! Configure a virtual router CE1.
host1(config)#virtual-router ce1
!
! Specify the interface for the LAG bundle lag 1 that groups all Ethernet physical
! interfaces between CE1 and PE1.
host1:ce1(config)#interface lag 1
!
! Add the Gigabit Ethernet physical interfaces to the LAG bundle named lag 1.
! Assign an IP address and mask to it.
host1:ce1(config-if)#member-interface gigabitEthernet 2/1/0
host1:ce1(config-if)#member-interface gigabitEthernet 2/1/3
host1:ce1(config-if)#ip address 7.7.7.7 255.255.255.0

Configuration on PE1 (Local PE Router)
Use the following commands on the local PE router (PE1) to configure the MPLS L2VPN
tunnel over LAG shown in Figure 123 on page 551.
! Configure a virtual router PE1.
host1(config)#virtual-router pe1
!
! Enable MPLS on a virtual router in Global Configuration mode.
host1:pe1(config)#mpls .
!
! Configure the LSR to create topology-driven LSPs. Enabling LDP automatically
! creates topology-driven LSPs.
host1:pe1(config)#mpls topology-driven-lsp
!
! On PE1, configure a loopback interface, and assign an IP address and mask to
! the interface.
host1:pe1(config)#interface loopback 0
