Configuring Layer 2 Protocol Tunneling: Example
This section includes configuration examples for L2PT in the forward and reverse modes.
Configuring L2PT in forward mode
This example shows how to configure L2PT in the forward mode:
At the customer facing router (encapsulation end):
!
interface GigabitEthernet0/1/0/1
negotiation auto
!
interface GigabitEthernet0/1/0/1.1 l2transport
encapsulation default
l2protocol cpsv tunnel
!
interface GigabitEthernet0/1/0/2
negotiation auto
!
interface GigabitEthernet0/1/0/2.1 l2transport
encapsulation default
!
