10.13 CONFIGURING IGMP

This switch uses IGMP (Internet Group Management Protocol) to query for any attached hosts
who want to receive a specific multicast service. The switch looks up the IP Multicast Group used
for this service and adds any port which received a similar request to that group. It then propagates
the service request on to any neighboring multicast switch/router to ensure that it will continue to
receive the multicast service. (For information about the use of IGMP snooping and multicast
filtering, refer to Appendix
10-8 Configuring and Monitoring the Switch
