MTU in martini is carried in LDP and in kompella in BGP NLRI as extended
In both case it has no effect to actual forwarding nor is it enforced by
padding signaling.
In JunOS martini/l2circuit you can configure arbitrary MTU to be signalled
in the LDP, so just configure on the JunOS end what ever MTU you need to
get the signaling up.
