To modify the RP threshold, complete the following tasks:
Specifying the Threshold Sample Interval
The threshold sample interval is the amount of time after which the PIM router
calculates the average rate of the current data flow. PIM uses the threshold sample
interval to determine the data threshold.
By default, the PIM router calculates the rate of the current data flow at 16-second
intervals. You can specify a value from 16 seconds through 300 seconds (5
minutes) to reduce the CPU load from calculation during data forwarding. If you
specify a sampling interval that is not a multiple of 16, the PIM router uses the
multiple of 16 lower than this value.
