IGMP
Introduction
Internet Group Management Protocol (IGMP) establishes and maintains the multicast group memberships between a Layer 3 multicast device and the hosts on the directly connected subnet.
IGMP has the following versions:
· IGMPv1—IGMPv1 manages multicast group memberships based on the query and response mechanism.
· IGMPv2—Backwards-compatible with IGMPv1, IGMPv2 has introduced a querier election mechanism and a leave-group mechanism.
· IGMPv3—Based on and compatible with IGMPv1 and IGMPv2, IGMPv3 enhances the control capabilities of hosts and the query and report capabilities of IGMP routers.
¡ IGMPv3 introduced two source filtering modes (Include and Exclude). These modes allow a host to receive or reject multicast data from the specified multicast sources.
¡ IGMPv3 introduces IGMP group-and-source queries and IGMP reports carrying group records.
¡ After IGMP is enabled on an interface, the interface can establish and maintain multicast group memberships.
