The fact that you need v4 space to build a MPLS backbone is a very good
reason to not waste a /10 on CGN crap.=20

Ideally, we would have a solution where an entire MPLS infrastructure
could be built without v4 space, demoting v4 to a legacy application
inside a VRF, but the MPLS standards wg seems content with status quo.
