ip pim
propagation-delay
This command configures the propagation delay required for a LAN prune delay
message to reach downstream routers. Use the no form to restore the default
setting.
ip pim propagation-delay milliseconds
no ip pim propagation-delay
milliseconds - The time required for a lan-prune-delay message to reach
downstream routers attached to the same VLAN interface. (Range: 100-
5000 milliseconds)
Default Setting
500 milliseconds
Command Mode
Interface Configuration (VLAN)
Command Usage
The override interval configured by the ip pim override-interval command and the
propagation delay configured by this 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 propagation
delay represents the time required for the lan-prune-delay message to be
propagated down from the upstream router to all downstream routers attached to
the same VLAN interface.
Example
Console(config-if)#ip pim propagation-delay 600
Console(config-if)#
