NOTE: This is not a complete router configuration.
With this configuration, broadcast packets inside frames arriving with VLAN identifier 10
on are normalized to a dual-tagged frame with an outer VLAN value of 200
ge-0/0/1
and an inner VLAN value of 100. The broadcast packet and frames egressing
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
an inner VLAN tag value of 100, also according to the configuration.
The same configuration can be accomplished more effectively using dynamic profiles.
Consider the following configuration, which uses dynamic profiles to manipulate VLAN
identifiers:

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 {
vpls-id 10;
neighbor 10.1.1.20 {
associate-profile green_vpls_pw_1; # The profile
}
}
{...more...}
