Enable IGMP

Specifies whether IGMP is enabled for multicast forwarding on this interface. Enabling IGMP on this interface allows the router to either listen for IGMP messages sent by hosts or forward IGMP messages received on other interfaces.

IGMP router

Specifies that IGMP router mode is enabled on this interface. An interface in IGMP router mode listens for IGMP messages from hosts and updates the TCP/IP multicast forwarding table.

IGMP proxy

Specifies that IGMP proxy mode is enabled on this interface. An interface in IGMP proxy mode acts as a host, forwarding IGMP host membership messages for all IGMP host membership messages received on all other interfaces on which IGMP router mode is enabled. Additionally, all nonlocal multicast traffic received on all other interfaces (on which IGMP router mode is enabled) is forwarded over the IGMP proxy mode interface.

IGMP protocol version

Lists the version of IGMP supported on this interface. This setting only applies when the interface is configured for IGMP router mode.
