Multicast: PIM signaling over VRFs and over MPLS

[EasyNetDev]

Hi,

I'm playing with multicast in a small LAB. There is a way to create PIM neighbors over MPLS or between VRFs?

Setup 2:
Server -> R01 vrf RED -> R01 vrf BLUE -> Client

Setup 2
Server -> R01 vrf RED -> MPLS + MP-BGP -> R02 vrf BLUE -> Client

There is end-to-end unicast connection between Server and Client. But I can't bring up the mutlicast.

I have no clue if is possible in FRRouting to do this. Any ideas?

I used PIM RP (Rendezvous Point) for PIM in RED and BLUE vrfs, but still can't see the traffic between endpoints.
