Introduction
Allied Telesis routers and managed layer 3 switches use IGMP—Internet Group Management
Protocol—to track which multicast groups their clients belong to. This enables them to send
the correct multimedia streams to the correct destination.
This How To Note describes basic and advanced IGMP configuration, in the following major
sections:
z an overview of IGMP and definitions of some of the IGMP terminology
z examples and discussion of the most common IGMP functionality—IGMP snooping, IGMP
Querier behaviour and selection, and IGMP proxy
z examples and discussion of the advanced functionality available through AlliedWare’s
feature-rich IGMP implementation
z information for debugging
z information about the STP state of the simple three-switch ring used in most examples
