I agree with general meaning of NG-MVPN.
But even with e.g. mLDP data-plane and BGP control plane there are plethora of options so one is not sure what is the topic of discussion.
As for the mLDP one could be using Default/Partitioned MDT along with P2MP/MP2MP tree.
And as for BGP control plane one could be using BGP-AD with or without BGP-C-MCAST.
So a lot of ambiguity even though we narrow the discussion down to mLDP data-plane and BGP control-plane.
