This command configures the propagation delay required for a LAN prune
delay message to reach downstream routers. Use the

the default setting.

The override interval configured by the ip pim override-interval command
and the propogation 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 propgated down from the upstream router
to all downstream routers attached to the same VLAN interface.
