Related Commands

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)#
