Command Reference Guide Tunnel Configuration Command Set

ip igmp

Use the ip igmp command to configure multicasting-related functions for the interface.

Syntax Description

immediate-leave	Specifies that if only one host (or IGMP snooping switch) is connected to
	the interface, when a leave is received, multicast of that group is
	immediately terminated as opposed to sending a group query and timing
	out the group if no device responds. Works in conjunction with ip igmp
	last-member-query-interval. Applies to all groups when configured.
last-member-query-interval	Controls the timeout used to detect whether any group receivers remain
<milliseconds>	on an interface after a receiver leaves a group. If a receiver sends a
	leave-group message (IGMP Version 2), the router sends a
	group-specific query on that interface. After twice the time specified by
	this command plus as much as one second longer, if no receiver
	responds, the router removes that interface from the group and stops
	sending that group's multicast packets to the interface. Range: 100 to
	65535 ms. Default: 1000 ms.
querier-timeout <seconds>	Specifies the number of seconds that the router waits after the current
	querier’s last query before it takes over as querier (IGMP V2). Range: 60
	to 300 seconds. Default: 2x the query-intervalvalue.
query-interval	Specifies the interval at which IGMP queries are sent on an interface.
<seconds >	Host query messages are addressed to the all-hosts multicast group
	with an IP TTL of 1. The router uses queries to detect whether multicast
	group members are on the interface and to select an IGMP designated
	router for the attached segment (if more than one multicast router
	exists). Only the designated router for the segment sends queries. For
	IGMP V2, the designated router is the router with the lowest IP address
	on the segment. Range: 0 to 65535 seconds. Default: 60 seconds.
query-max-response-time	Specifies the maximum response time advertised by this interface in
<seconds>	queries when using IGMP V2. Hosts are allowed a random time within
	this period to respond, reducing response bursts. Default: 10 seconds.
static-group	Configures the router's interface to be a statically-connected member of
<group-address>	the specified group. Packets received on the correct RPF interface are
	forwarded to this interface regardless of whether any receivers have
	joined the specified group using IGMP.
version [1 2]	Sets the interface’s IGMP version. The default setting is version 2.
