7. on page 49 About IP multicast and IGMP IP hosts use IGMP and IP multicast addressing to report their group memberships to immediate neighboring multicast routers Routers send IGMP queries to all hosts and IGMP hosts respond by sending IGMP reports to the multicast address of the group they want to participate in The switch uses the information learned from IGMP activity to map IP multicast groups to switch ports Packets destined to a particular multicast group are delivered only to those member ports Note The Business Policy Switch 2000 and BayStack 450 product group are neither IGMP routers nor IGMP hosts The IGMP snooping feature optimizes IP multicast in a bridged Ethernet environment Configuring Business Policy Switches with Optivity Quick2Config 46 Chapter 3 Configuring IGMP snooping IGMP host membership reports IP multicast routers use IGMP to learn about the existence of host group members on their directly attached subnets The IP multicast routers get this information by broadcasting IGMP queries and listening for IP hosts reporting their host group memberships This process is used to set up a client server relationship between an IP multicast source that provides the data streams and the clients that want to receive the data The client server path is set up as follows 1 The designated router sends out a host membership query to the subnet and receives host membership reports from end stations on the subn
