[j-nsp] Nextgen Multicast on MX boxes

[Gordon Smith]

 Hi all,

 I'm after some advice on setting up nextgen multicast on an RSVP based 
 MPLS network.

 The network is quite simple - MX5's with static lsp's, rsvp signalling 
 & fast reroute.

 But setting up multicast over this is not something I'm very familiar 
 with.
 I've looked at the Juniper extranet doc, but it's not exactly clear 
 with explanations of why the configs are done that way.
 e.g. if I want to pass a stream from one vrf to another vrf on the same 
 router, I need to configure a vt- interface. That's fine, but what (if 
 any) additional steps
 are required to actually establish a stream between the 2 vrf's?

 The routers are set up as redundant pairs (vrrp between interfaces) - 
 is PIM sparse my best option, or should I be looking to anycast for 
 redundancy, or something else?
 Can I dictate the group membership at the router, or do the endpoints 
 need to be statically configured for the correct group membership?
 The docs show both ldp & rsvp configured together - is the mLDP 
 functionality a requirement to get mvpn to work correctly?

 Sorry for all the questions. Trying to get a better understanding on 
 what the best solution is and what the box limitations are


 Cheers,
 Gordon
