Use the following commands on the local PE router (PE1) to configure the MPLS L2VPN tunnel over LAG shown in Figure 123.
- ! 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. Configure MPLS tunneling on this
side of the connection by
- ! issuing the mpls-relay command.
When you issue the mpls-relay command, you
- ! must use a reachable local IP address and the same VC
ID value (1) on both
- ! sides of the connection.
- 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)#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
