Specifying a Version Threshold Time
By default, 540 seconds can elapse after IGMP detects a Version 1 query before
IGMP tries to become the designated querier.
The value you specify should be greater than the Version 1 query rate of all IGMP
speakers on all networks directly connected to the router.
You can use the BCC or Site Manager to specify a version threshold time from
1 second to 65,535 seconds.
Using the BCC
Navigate to the global IGMP prompt and enter
version-threshold
threshold
threshold is the number of seconds from 1 to 65,535.
For example, the following command sets the version threshold time to 500
seconds:
igmp# version-threshold 500
igmp#
