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.
