Enable the Immediate-Leave feature only on receiver ports to which a single receiver device is connected. IP multicast traffic uses group addresses, which are Class D IP addresses. When a subscriber selects a channel, IGMP is a protocol used by network equipment to specify which devices should receive which multicast groups.

Learn more about how Cisco is using Inclusive Language. If IGMPv3 is used in a network, CGMP will continue to work, but CGMP fast-leave support is ineffective and the following conditions apply: Each time a host on a new port of the CGMP switch joins a multicast group, that port is added to the list of ports to which the traffic of this group is sent. Documentation website requires a Cisco.com user ID and password. A host is a receiver, including routers, that sends report messages (in response to query messages) to inform the querier of a host membership. Querier for IGMP.
