This command configures the override interval, or the time it takes a
downstream router to respond to a lan-prune-delay message. Use the
no
form to restore the default setting.

milliseconds - The time required for a downstream router to
respond to a lan-prune-delay message by sending back a Join
message if it wants to continue receiving the flow referenced in the
message. (Range: 500-6000 milliseconds)

The override interval configured by this command and the propogation
delay configured by the
ip pim propagation-delay command are used to
calculate the LAN prune delay. If a downstream router has group members
which want to continue receiving the flow referenced in a LAN prune delay
message, then the override interval represents the time required for the
downstream router to process the message and then respond by sending a
Join message back to the upstream router to ensure that the flow is not
terminated.
