Hi All, we are deploying multicasting in my network over wan & LAN. now we are confused about multicast redundancy for same groups. We have a DR site which is replica of main site with same hardware & configuration. we have deployed sparse-dense mode with static RP. Its working fine but if the main site goes down multicast should work properly from DR site where we have same multicast source as main site with the same group IP. I tried to implement MSDP but it is not working. I want to use redundancy in my network. I am attaching the nw diagram for your reference.

Any help would be gr8.
