[j-nsp] Pushing traffic from an l2circuit into a routing-instance

You need a Tunnel PIC in your T-series router and you will have 
bandwidth constraint according to type of PIC you use.
Use "lt" interfaces to terminate this l2circuit and put the traffic into 
VPLS instance:

interfaces {
    lt-1/2/0 {
        unit 0 {
            description l2circuit_termination;
            encapsulation ethernet-ccc;
            peer-unit 1;
            family ccc;
        unit 1 {
            description vpls_instance;
            encapsulation ethernet-vpls;
            peer-unit 0;
