 Ph-0: IPv4 only
 Ph-1: IPv4/v6 dual stack + v4/v6 coexistence technologies
 Ph-2: IPv6 only

I suppose MPLS v6 control plane would become necessary at Ph-2, or a
later stage of Ph-1.

In the meantime, MPLS can be viewed as one of the v4/v6 coexistence
technologies. IPv6 traffic can be carried over v4 signaled MPLS LSP in
various ways (i.e. 6PE/6VPN, static mapping onto TE-LSP, IGP
