Configuring L2 Tunnels MPLS Configuration
L2 Tunneling Based on VLAN ID Configuration Examples
The FEC-to-label binding for a virtual circuit can be based on the VLAN ID assigned to a customer by a service
provider.
Figure 17-16 shows a customer VLAN with an ID of 100, and another customer VLAN with an ID of 200.
The VLANs are mapped to VC labels that are distributed via LDP. LDP-signaling VLANs carry the signaling
necessary to establish the LDP connection. For example, the ports at each end of the link between R1 and R2 are
configured with VLAN ID 110, while the ports at each end of the link between R2 and R3 are configured with VLAN
ID 120. The tunnel LSP can use either LDP or RSVP as the signaling protocol; configuration commands for both LDP
and RSVP signaling are shown.

The following is the configuration for R1:
! Configure router loopback
interface add ip lo0 address-netmask 111.1.1.1/32
! Make gi.4.1 a trunk port
vlan make trunk-port gi.4.1
! Configure the VLAN cust1 with a VLAN ID of 100
vlan create cust1 port-based id 100
vlan add ports gi.6.1, gi.4.1 to cust1
! Configure the VLAN cust2 with a VLAN ID of 200
vlan create cust2 port-based id 200
vlan add ports gi.3.1,gi.4.1 to cust2
