IGMP Proxy Commands

IGMP Proxy is used by the router on IPv4 systems to enable the system to 

issue IGMP host messages on behalf of hosts that the system discovered 

through standard IGMP router interfaces, thus acting as proxy to all its hosts 

residing on its router interfaces.
PowerConnect supports IGMP Version 3, Version 2 and Version 1. Version 3 

adds support for source filtering [SSM] and needs to be interoperable with 

Versions 1 and 2. Version 2 supports the group membership terminations to 

be quickly reported to overcome leave latency and is designed to be 

interoperable with Version 1.

This chapter explains the following commands:

Use the ip igmp-proxy command in Interface Configuration mode to enable 

the IGMP Proxy on the router. To enable the IGMP Proxy on the router, 

multicast forwarding must be enabled and there must be no multicast routing 

protocols enabled on the router.
