Rosen mVPN and NG-nVPN together?

We're currently using Rosen mVPN in a pure C6k/Sup720 network and are
happy about it. We might end up in a situation where we need to
introduce e.g. Juniper equipment and are wondering if Rosen mVPN and
NG-mVPN can coexist.

Having the two multicast domains interface with each other via non-MPLS
interfaces in a couple of places should work as far as I can tell, but
it would potentially introduce scalability problems.

Is there some smart way of making Rosen mVPN and NG-mVPN coexist? My
google-fu doesn't turn up anything, but I'm not sure what to look for.

They should behave like ships in the night but I can't think of any smart
way of how to interwork gre and mpls-te other than via non-labeled
interfaces
Oh and don't forget the "mpls traffic-eng multicast-intact" :)

You are presumably aware that JunOS can do rosen MVPN, so if you're
happy with it, you can just stick with it?

My thought also.

We don't use autoroute-announce, so it shouldn't be needed. But I'll
keep it in mind if we ever start using TE more. :-)

Ah, actually I wasn't! That does make the scenario much easier to
handle. Thanks for pointing that out.

A bit of googling points at most vendors supporting Rosen/RFC6037 so I
guess it's really a no brainer. One day when maybe all of our routers
support NG-mVPN we can make the switch.

Unfortunately, I can't get into the details as it's still in
development, but one of the major vendors implementing NG-
MVPN already have numerous options of inter-working NG-MVPN
with Rosen MVPN's.

They aren't necessarily pretty, but they'd get you limping
until your network is fully migrated.
