I think I have tried something like this. I don't use it though. I still 
do not have EX'es.
You should have an L3 card on MX and you must sacrifice a 10GE port for
tunneling or use an internal tunnel port on card with 1GE interfaces.

Than try something like this:


lt-4/3/0 {
    description "tunnel interface";
    unit 3 {        
        description "PeterP tunnel L2";
        encapsulation vlan-ccc;
        vlan-id 16; 
        peer-unit 4;
    }               
    unit 4 {        
        description "PeterP tunnel L3";
        encapsulation vlan;
        vlan-id 16; 
        peer-unit 3;
        family inet {
            address 195.150.0.129/30;
        }           
    }               


L2V-c480pd-c480l {
    instance-type l2vpn;
    interface lt-4/3/0.3;
    route-distinguisher 195.150.0.243:2000;
    vrf-import L2V-pp-import;
    vrf-export L2V-pp-export;
    protocols {
        l2vpn {
            encapsulation-type ethernet-vlan;
            site c480pd {
                site-identifier 1;
                interface lt-4/3/0.3 {
                    remote-site-id 2;
                }   
            }       
        }           
    }               
}                   

policy-options policy-statement L2V-pp-export 
term def {
    then {
        community add L2V-pp;
        accept;
    }
}
term reject {
    then reject;
}
