At this time (on Junos anyway, which I have more experience 
with re: NG-MVPN), you can transport IPv6 Multicast traffic 
in an NG-MVPN. I should expect Cisco and ALU have an 
implementation as well.

It is based on 6VPE, really, since the "VPN" portion of NG-
MVPN is really just a Unicast l3vpn instantiation.

Of course, it is my hope that native MPLSv6 will also add  
support for p2mpv6 and mp2mpv6 scenarios over SR, which will 
enable true/native NG-MVPNv6 (dual-stack, of course, shared 
within a single NG-MVPN VRF, of course). 

Given that LDPv6 and RSVPv6 have poor vendor interest at the 
moment, you can be reasonably confident mLDPv6 or p2mp RSVP-
TEv6 will never see the light of day either. So yes, SR is 
probably where we want to be pushing for this from vendors 
as well.
