To modify the default value for the IGMP query interval, enter the following.

Syntax: ip igmp query-interval <10-3600>
The interval must be a little more than two times the group membership time.
Setting the group membership time
Group membership time defines how long a group will remain active on an interface in the absence
of a group report. Possible values are from 20 – 7200 seconds and the default value is 260
seconds.
To define an IGMP membership time of 262 seconds, enter the following.
BigIron RX(config)# ip igmp group-membership-time 262
Syntax: ip igmp group-membership-time <20-7200>
Setting the maximum response time
The maximum response time defines the maximum number of seconds that a client can wait
before it replies to the query sent by the router. Possible values are 1 – 10. The default is 10.
To change the IGMP maximum response time, enter a command such as the following at the global
CONFIG level of the CLI.
BigIron RX(config)# ip igmp max-response-time 8
Syntax: [no] ip igmp max-response-time <num>
The <num> parameter specifies the maximum number of seconds for the response time. Enter a
value from 1 – 10. The default is 10.
