PurposeCommand or Action
Example:
Router(config-if)# ip pim
query-interval 1
•
Perform this step only on redundant routers on the edge of a PIM domain.
•
The default query interval is 30 seconds.
•
The period argument is in seconds unless the msec keyword is specified.
•
Set the query interval to a smaller number of seconds for faster convergence,
but keep in mind the trade-off between faster convergence and higher CPU
and bandwidth usage.

The following example shows how to:
•
Set the query interval to 1 second for faster convergence.
•
Configure the router to never move to the SPT but to remain on the shared tree.
•
Set a limit of 10 PIM sparse mode register messages sent per second for each (S, G) routing entry.
