Configuration on CE1 (Local CE Router)
Use the following commands on the local CE router (CE1) to configure the MPLS L2VPN
tunnel shown in Figure 122 on page 547.
! 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.
host1:ce1(config-if)#member-interface gigabitEthernet 2/1/0
host1:ce1(config-if)#member-interface gigabitEthernet 2/1/3
!
! Specify VLAN as the encapsulation method for the Ethernet interface.
host1:ce1(config-if)#encapsulation vlan
!
! Specify another subinterface in the LAG bundle lag 1.1.
host1:ce1(config-if)#interface lag 1.1
!
! Assign an S-VLAN ID and a VLAN ID for the subinterface, and assign an IP
! address and mask to the interface.
host1:ce1(config-subif)#svlan id 1 1
host1:ce1(config-subif)#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 shown inFigure 122 on page 547.
! Configure a virtual router PE1.
host1(config)#virtual-router pe1
!
! Enable MPLS on a virtual router in Global Configuration mode.
host1:pe1(config)#mpls .
