I think that should only be an option. Mandatory hair-pinning of traffic
is terribly inefficient when the nodes are adjacent at layer two and
therefore could take to each other directly (at layer 2 and 3).

So how are we going to run IPv4 over it, with our own address space, if

What if we want to run a MPLS LER at a SME's site - do we have to
encapsulate MPLS in GRE in IPv6?
