NOTE: This is not a complete router configuration.

With this configuration, broadcast packets inside frames arriving with VLAN identifier 10

on ge-0/0/1 are normalized to a dual-tagged frame with an outer VLAN value of 200

and an inner VLAN value of 100. The broadcast packet and frames exiting ge-0/0/2 or

ge-0/0/3 have the outer VLAN value stripped and the inner VLAN value swapped to 20

and 30 respectively, according to the interface configuration. However, this stripping of

the outer VLAN tag and the swapping is extra work, because the frames will still egress

the VPLS pseudowire in routing instance green with an outer VLAN tag value of 200 and

an inner VLAN tag value of 100, also according to the configuration.

The same configuration can be accomplished more effectively using dynamic profiles.

VPLS Pseudowire Interfaces and Dynamic Profiles

Consider the following configuration, which uses dynamic profiles to manipulate VLAN

identifiers:

[edit routing-instances]

green {

instance-type vpls;

interface ge-0/0/1.1;

interface ge-0/0/2.1;

interface ge-0/0/3.1;

vlan-id 100; # Desired inner VLAN tag on the VPLS pseudowire

protocols vpls {
