Configures the amount of time a forwarding entry can remain unused before the device deletes it.
The default inactive time is 180 seconds.
PIM router configuration mode
A device deletes a forwarding entry if the entry is not used to send multicast packets. The PIM inactivity timer defines how long a forwarding entry can remain unused before the device deletes it.
The no inactivity-timer form of this command restores the default inactive time of 180 seconds.
This example configures an inactive timer of 90 seconds for IPv4 PIM.
device# configure terminal device(config)# router pim device(config-pim-router)# inactivity-timer 90
