Internet Group Management Protocol

The Internet Group Management Protocol (IGMP) is used by IPv4 systems (hosts and routers) to report
their IP multicast group memberships to any neighboring multicast routers. The PowerConnect
M6220/M6348/M8024 performs the multicast router role of the IGMP protocol, which means it collects
the membership information needed by the active multicast routing. The currently supported multicast
routing protocols in the PowerConnect M6220/M6348/M8024 are DVMRP, PIM-DM, and PIM-SM.
The PowerConnect M6220/M6348/M8024 supports IGMP Version 3. Version 3 adds support for source
filtering, which is the ability for a system to report interest in receiving packets only from specific source
addresses, as required to support Source-Specific Multicast [SSM], or from all but specific source
addresses, sent to a particular multicast address. Version 3 is designed to be interoperable with Versions 1
and 2.
