Displays the IP multicast address or range of IP multicast addresses, use the the ability for a host to signal desire to leave a multicast group and IGMPv3 When an IGMPv2 router receives a General Query message, the election of IGMPv2 Querier starts by comparing the source IP address in the message with its own interface address. Enable an IGMP Version 3 (IGMPv3) host stack so that the router can function as a multicast network endpoint or host.
