Does any vendor support the MPLS for native IPv6 network?
Unfortunately noone of the major vendors have yet implemented MPLS control plane via IPv6 transport. From my understanding, the protocol specs are there, just no implementation.
So for now, you still have to use IPv4 for the MPLS network control plane and must either forward IPv6 natively dual-stack alongside IPv4, or transport IPv6 via 6(V)PE.
"no customer demand", as usual. It's just us weirdos trying to do such things. :)
Correct, LDP etc. must all be done at IPv4. That can do the MPLS label bits, and IPv6 can then be carried inside MPLS. If you use 10.0.0.0/8 for numbering your point to point links, you get 4-8M links, dependant on whether you do /30 or /31. I don't imagine that represents a problem for many people. -- Nathan Ward
