Hi Bilal,

I think I'd use an IP Anycast RP approach having an Anycast RP in each site and the other multicast routers in your environment configured with a static RP of the Anycast RP address. To finish things off, you peer the two Anycast RPs using Multicast Source Discovery Protocol (MSDP).

This solution would give you load sharing of the registrations across the two RPs (assuming sources in both sites), the RP is in the same site as the sources/receivers and you get rapid convergence i.e., the speed of your IGP, in the event of a failure of one of the devices acting as the RP.

There's a more detailed explanation and configuration example in the Anycast RP white paper.

Regards
