IGMP is used to learn the multicast group membership of the hosts connected to a router. Multicast routing protocols, like PIM, use this information to forward multicast packets that are received by the router. An IGMP proxy learns group membership and forwards multicast traffic based on this information. It does not need to run any multicast routing protocols.
