Internet – IGMP Proxy

The Internet Group Management Protocol (IGMP) is an Internet protocol that provides a way for an Internet computer to report its multicast group membership to adjacent routers.

The hosts interact with the system through the exchange of IGMP messages. When you want to configure IGMP proxy, the system will interact with other routers through the exchange of IGMP messages. However, when acting as the proxy, the system performs the host portion of the IGMP task as follows:

•When being queried, the system will send membership reports to the group.

•When one of the hosts joins a multicast address group which none of other hosts belongs to, the system will send unsolicited membership reports to that group.

•When the last host in a particular multicast group leaves the group, the system will send a leave group membership report to the router’s group.
