Example of bad choices for timer values > Problem 3: Default Timeout Interval too short

Note that the Query Response Interval is specified in 1/10 second units on the command line and in output of show ip igmp, but in units of seconds in the above formula. In this example, the Query Response Interval was set with queryresponseinterval=5, so is 0.5 seconds.

Automatic Since software versions 281-03 and 2.9.1, IGMP automatically changes the Default Timeout changes Interval if you change any of the Robustness Variable, the LMQC, the Default Query Interval, or the Query Response Interval. You can override the setting, as in this example, but we do

not recommend this.

Before these releases, if you changed any of these other timers or counters, you had to manually calculate and change the Default Timeout Interval yourself.

For more information, see "Synchronisation of timers" on page 78.
