MST BPDU Tunneling in Vpls

I m trying to build VPLS in ring topology, where ce (PE1=CE1=CE2=CE3=PE2) switches are connected in ring and terminated on two PE routers. In ce ring I got MST running. Below is configuration of PE vpls instances and ce facing interface. Is it possible to tunnel bpdu s in VPLS instance ?

 

PE1

Customer1 {
    instance-type vpls;
    vlan-id all;
    interface ge-1/1/4.1;
    route-distinguisher 10.0.0.3:2077;
    vrf-target target:65001:2077;
    protocols {
        vpls {
            site-range 10;
            no-tunnel-services;
            site ALL {
                site-identifier 3;
                multi-homing;
                interface ge-1/1/4.1;
            }
            mac-flush {
                any-interface;
            }
        }
    }
}

 

ge-1/1/4

flexible-vlan-tagging;
encapsulation flexible-ethernet-services;
unit 1 {
    encapsulation vlan-vpls;
    vlan-id-range 1-3000;
    family vpls;
}

Re: MST BPDU Tunneling in Vpls

Hi by the looks of it, vpls by default will pass standards based bpdus, but not proprietary bpdus. So having STP setup on each CE side should do the trick. Link below discusses this very same thing...

You could also look into dot1q tunneling to tunnel additional services and preserve the CE vlan-id header by shimming an outer tag, this is supported on a single VPLS instance, and link for that should be below...
