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.


! 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 

host1:pe1(config-if)#ip address 11.11.11.11
255.255.255.255 

!
! Assign the router ID using the IP address you configured
for the loopback 
! interface.
host1:pe1(config)#ip router-id 11.11.11.11 

!
! Create an IEEE 802.3ad LAG bundle, lag2, and add the
Gigabit Ethernet physical  
! interfaces to lag2. Specify VLAN as the encapsulation
method for the member  
! interfaces.
host1:pe1(config)#interface lag 2 

host1:pe1(config-if)#member-interface gigabitEthernet
2/1/1 

host1:pe1(config-if)#member-interface gigabitEthernet
2/1/2 

host1:pe1(config-if)#encapsulation vlan

!
! Specify a subinterface by adding a unique subinterface
number to the LAG bundle  
! name. Assign an S-VLAN ID and a VLAN ID for the subinterface.
Also, configure  
! MPLS tunneling.
host1:pe1(config-if)#interface lag 2.1 

host1:pe1(config-subif)#svlan id 1 1 

host1:pe1(config-subif)#mpls-relay 22.22.22.22
1

!
! Create another Gigabit Ethernet interface on PE1, specify
VLAN as the  
! encapsulation method, and configure another subinterface.
For this subinterface,  
! assign a VLAN ID, specify the encapsulation method as
VLAN, configure MPLS,  
! and assign an IP address and mask. Also, enable LDP and
topology-driven LSP, as  
! does any LDP-related command, using an implicit default
profile, on this Gigabit  
! Ethernet subinterface.
host1:pe1(config)#interface gigabitEthernet
2/1/4

host1:pe1(config-if)#encapsulation vlan 

host1:pe1(config-if)#interface gigabitEthernet
2/1/4.1 

host1:pe1(config-subif)#vlan id 20 

host1:pe1(config-subif)#ip address 2.0.0.1
255.255.255.0 

host1:pe1(config-subif)#mpls 

host1:pe1(config-subif)#mpls ldp

!
! Configure a static route with the destination IP address,
mask, and IP address of  
! the next hop that can be used to reach the destination
network. 
host1:pe1(config)#ip route 22.22.22.22 255.255.255.255
2.0.0.2 

! 
! Configure LDP to advertise a non-null label for the egress
routes. 
host1:pe1(config)#mpls ldp egress-label non-null
