We want to setup multicast VPN on the service providers MPLS backbone.
Our setup is we have a DC and DR site. Primarily all the remote sites will connect to DC site and in case DC site fails remote sites will connect to DR site.
Requirement is to connect seamlessly from DC to DR with multicast application switchover.
How can we achieve this can there be Multiple RP address for the multicast registration.
The routing between DC and DR by advertising same /24 block of IP address to DC and DR using BGP local preference and making DC site primary over DR site.
For reference attaching the network topology.
For clarification pls speak.
