Modifying the IGMP Host-Query Message Interval

The IGMP querier router periodically sends general host-query messages. These messages solicit group membership information and are sent to the all-systems multicast group address, 224.0.0.1.

By default, host-query messages are sent every 125 seconds. You can change this interface to change the number of IGMP messages sent on the subnet.

To modify this interval, include the query-interval statement:




query-interval seconds;

You can include this statement at the following hierarchy levels:

[edit protocols igmp]
[edit logical-systems logical-system-name protocols igmp]

The query interval value can be from 1 through 1024 seconds.
