I’ve a generic multicast question: I've got 2 sources active/active sending the same multicast group on a network with one receiver receiving the multicast group, without choosing the source (IGMP v2).
In the actual situation, if the client does not choose the source, it receives both streams and it is not OK. So the idea would be to receive only one multicast from only one source and If one source is NOK, the receiver get the multicast from the other source.
What is the best solution to do that?
I've looked at SSM but it's IGMP v3 based and client must specify the source, this is not the case here. Anycast + PIM or MSDP seems to be the solution but it seems complex for my "simple" need:
