hi

I want to find out about the following scenario and how to set it up.

we will have multiple customers connected an an access switch with a Q-in-Q trunk port heading back to an MX box.

we want to place the customers frames into a seperate VPLS instance depending on the outer Qtag.  The Outer Qtag is simply for customer seperation at each access switch.

Can this be done and what do I need?

thanks

This config should work.

jnpr@Themis-MX960-RE0# show interfaces ge-4/0/3
flexible-vlan-tagging;
encapsulation flexible-ethernet-services;
unit 10 {
    encapsulation vlan-vpls;
    vlan-tags outer 10 inner 5;
    family vpls;
}

[edit]
jnpr@Themis-MX960-RE0# show routing-instances
VPLS {
    instance-type vpls;
    vlan-id all;
    interface ge-4/0/3.10;
    protocols {
        vpls {
            encapsulation-type ethernet-vlan;
            no-tunnel-services;
            vpls-id 10;
            neighbor 2.2.2.2;
        }
    }
}

This is LDP-based VPLS

note the vlan protocol id on the MX is 0x8100 for both tags. You could change it if you want.

wow

thanks for the detailed answer, 

follow up questions:

1. vlan-tags outer 10 inner 5 = If I want to include all inner customer tags? [.*]?
