IGMP Configuration
This chapter describes the IGMP Configuration set of commands and how to use them.
10.1 IGMP CONFIGURATION SUMMARY
Multicasting is used to support real-time applications such as video conferences or streaming audio.
A multicast server does not have to establish a separate connection with each client. It merely
broadcasts its service to the network, and any hosts that want to receive the multicast register with
their local multicast switch/router. Although this approach reduces the network overhead required
by a multicast server, the broadcast traffic must be carefully pruned at every multicast switch/router
it passes through to ensure that traffic is only passed to the hosts that subscribed to this service.
The Matrix E1 switch device uses IGMP (Internet Group Management Protocol) to query for any
attached hosts who want to receive a specific multicast service. The device looks up the IP Multicast
Group used for this service and adds any port that 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 more information about the use of IGMP snooping, refer to Section 10.3.
