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 router through the exchange of IGMP messages. However, when acting as the proxy, the system performs the host portion of the IGMP task as follows:
¾When it is queried, the system will send group membership reports to the group.
¾When one of the hosts joins a multicast address group to which none of other hosts belong, the system will send unsolicited group membership reports to that group.
¾When the last of hosts in a particular multicast group leaves the group, the system will send a leave group membership report to the routers group.
