Operators that prefer to keep unicast and multicast traffic on separate links in a network have the option to maintain two separate instances of the route table (unicast and multicast) per VPRN.
Multicast BGP can be used to advertise separate multicast routes using Multicast NLRI (SAFI 2) on PE-CE link within VPRN instance. Multicast routes maintained per VPRN instance can be propagated between PE-PE using BGP Multicast-VPN NLRI (SAFI 129).
SR OS supports option to perform RPF check per VPRN instance using multicast route table, unicast route table or both.
Non-congruent unicast and multicast topology is supported with NG-MVPN. Draft Rosen is not supported.
