Protocol Description These sections describe IGMP and an example topology: IGMP Protocol on page 5 IGMP Topology on page 5 IGMP Protocol IGMP is used to learn the multicast group membership of the hosts connected to a router. Multicast routing protocols, like PIM, use this information to forward multicast packets that are received by the router. An IGMP proxy learns group membership and forwards multicast traffic based on this information. It does not need to run any multicast routing protocols. IGMP Topology The following illustration shows an example topology using an IGMP proxy. This example topology is referenced in all of the procedures in this guide. The IGMP proxy device performs the router portion of IGMP on the downstream (host) interfaces and the host portion of IGMP on the upstream (router) interfaces. The IGMP proxy device consolidates the reports received on the downstream interfaces and sends summarized reports on the upstream interface. The main use for IGMP proxy is in edge devices. 5
