Cisco IOS XR L2VPN Local Bridging

Sub-Interface configurations can be done by translating tags or popping vlan tag:

First option:

interface GigabitEthernet0/0/0/10.1 l2transport
 encapsulation dot1q 10
 rewrite ingress tag translate 1-to-1 dot1q 20 symmetric

interface GigabitEthernet0/0/0/11.1 l2transport
 encapsulation dot1q 20
 rewrite ingress tag translate 1-to-1 dot1q 10 symmetric

Second Option:

interface GigabitEthernet0/0/0/10.1 l2transport
 encapsulation dot1q 10
 rewrite ingress tag pop 1 symmetric

interface GigabitEthernet0/0/0/11.1 l2transport
 encapsulation dot1q 20
 rewrite ingress tag pop 1 symmetric
