ip pim override-
interval
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.
SYNTAX
ip pim override-interval milliseconds
no ip pim override-interval
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)
DEFAULT SETTING
2500 milliseconds
COMMAND MODE
Interface Configuration (VLAN)
COMMAND USAGE
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.
EXAMPLE
Console(config-if)#ip pim override-interval 3500
Console(config-if)#
