I have two sources multicasting for the same group. Network connectivity is as follows:
source s1 (on vlan X) and s2 (on vlan Y)------multicast router------Receiver (on vlan Z)
Receiver is using IGMP V2 to join the group. Given the fact that Multicast Router can see both sources for the same group, how is Multicasting router supposed to select which (S,G) channel should be used for forwarding multicast to receiver?
