Protocol Description

These sections describe IGMP and an example topology:

■ “IGMP Protocol” on page 5

■ “IGMP Topology” on page 5

IGMP ProtocolIGMP is used to learn the multicast group membership of the hosts connected to arouter. Multicast routing protocols, like PIM, use this information to forwardmulticast packets that are received by the router. An IGMP proxy learns groupmembership and forwards multicast traffic based on this information. It does notneed to run any multicast routing protocols.

IGMP TopologyThe following illustration shows an example topology using an IGMP proxy. Thisexample 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 downstreaminterfaces and sends summarized reports on the upstream interface. The main use forIGMP proxy is in edge devices.
