Unless there is operational assurance of some size X>1280, however, tunnels have to use fragmentation to guarantee that - at a minimum - packets up to 1280 will get through.
In that case there really needs to be a note about MPLS.You can fragment into an IP tunnel, but not an MPLS tunnel, because you cannot fragment the payload as you can in IPv4 and you cannot fragment MPLS.
