IGMP is used by IP hosts and adjacent multicast routers to establish multicast groupmemberships.Internet Group Management Protocol (IGMP) Snooping is the process of listening to IGMP network traffic. It is a featurethat allows a layer 2 switch to “listen in” on the IGMP conversation between hosts and routers by processing the layer 3IGMP packets sent in a multicast network.4.10.0.1 Types of IGMP Snooping:There are two types of IGMP Snooping.Active IGMP Snooping:Active IGMP Snooping listens to IGMP traffic and filters IGMP packets to reduce load on the multicast router. Joins and leavesheading upstream to the router are filtered so that only the minimal quantity of information is sent.Passive IGMP Snooping:Passive IGMP Snooping simply listens to IGMP traffic and does not filter or interfere with IGMP.Tsunami QB-8100 Series (50 Mbps / 12 Mbps) Installation and Management Guide 102
