We are running NG-MVPN (BGP replaces PIM, MPLS replaces 

We run PIM-SM, not only because our customer's STB's only 
support IGMPv2 (we only transport IPTv content, not generate 
it), but also because, well, it just works and there hasn't 
been any compelling need to push for PIM-SSM.

It's scaling well due to the nature of the NG-MVPN 
infrastructure itself.
