Internet Group Internet Group Management Protocol (IGMP) is a protocol that runs Management between hosts and their immediate neighboring multicast routers. The
Protocol protocol allows a host to inform its local router that it wishes to receive transmissions addressed to a specific multicast group. Based on group membership information learned from the IGMP, a router is able to determine which if any multicast traffic needs to be forwarded to each of its subnetworks.
