The MIB module for IGMP Snooping feature. Internet Group Management Protocol (IGMP) is the protocol used by IPv4 end hosts to indicate their interest in receiving multicast traffic for certain multicast groups to neighboring multicast routers. Version 3 of IGMP adds support for source based filtering; which means the end hosts can specifically indicate to receive or not-receive multicast packets from specific source addresses. This information is used by the multicast routers to restrict forwarding of multicast traffic for the host. IGMP Snooping is a switch protocol. A switch that implements IGMP Snooping listens to the IGMP messages exchanged between the hosts and router, then provides selective transmission of multicast traffic based on multicast mac destination address or multicast group address. With IGMPv3 support, IGMP Snooping can potentially provide selective transmission of multicast data based on (source address, group address) onto the ports that are interested. In addition to this, IGMP Snooping can also provide proxy reporting, report suppression and fast leave capabilities.
