Just look at this:
http://www.juniper.net/techpubs/software/junos/junos90/mx-solutions-guide/one-vpls-instance-for-several-vlans.html#id-vpls-many-vlans
One VPLS Instance for Several VLANs
routing-instances { 
customer-c1-v1-to-v1000 { 
instance-type vpls; 
vlan-id all; # Note the use of the VLAN id all statement 
interface ge-1/0/0.1; 
interface ge-2/0/0.1; 
interface ge-3/0/0.1;  



I am ot sure that's the solution but perhaps it can help
Regards
Alain

Objet : [j-nsp] question regarding multiple interfaces in vpls (vlan-tagswap used)

Hi all,

I am having problems with VPLS again, and would like to ask for your help.

Basically, I have multiple VPLS sites, each sites may host a few interfaces.

The configure looks like this:

interfaces {
    ge-0/1/0 {
        unit 0 {
            encapsulation vlan-vpls;
            vlan-id 513;
            input-vlan-map pop;
            output-vlan-map push;
        }
        unit 1 {
            encapsulation vlan-vpls;
            vlan-id 514;
            input-vlan-map pop;
            output-vlan-map push;
        }
    }
}

routing-instances {
    VPLS.0 {
        instance-type vpls;
        interface ge-0/1/0.0; // doesn't work when both enabled
        interface ge-0/1/0.1;
        route-distinguisher 7777:0;
        vrf-target target:7777:0;
        protocols {
            vpls {
                site-range 40;
                site PE.2 {
                    site-identifier 2;
                }
            }
        }
    }
}


This doesn't work though, unless I only enable one of the interfaces in the VPLS interface for every site.
Can anyone explain what's going on here and how I can fix it?

Thanks a lot!

-Simon
