Basic port mode Martini tunnel, one end (we have several of these):

interfaces {
    fe-0/3/0 {
        mtu 1568;
        encapsulation ethernet-ccc;
        unit 0;

protocols {
    ldp {
        interface lo0.0;
    l2circuit {
        neighbor a.b.c.d {
            interface fe-0/3/0.0 {
                virtual-circuit-id 42;

Also, you need LSPs between the routers - these can be setup using
either LDP or TE/RSVP.

Given that there is both PB-1GE-LH and PB-1GE-LX-B in the price list,
and the latter specifically mentions "supports CCC-for-VLANs" while
the former does not (and correspondingly for the PE- PICS), I would
definitely check with JTAC if you have the PB-1GE-LH or the PE-1GE-LH.
