Suppose that no multicast traffic has flowed in a LAN segment. The multicast routing protocol operates in sparse-mode. If a host wants to join a group, it sends a group report to the group address, but how does the local router receives this report if the router is not listing to this address group?
If the router is running PIM on an interface that also enables IGMP. So the router will receive the IGMP join message on the interface and then send a join request to the RP (Rendevous Point) asking to be sent the multicast traffic.
