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
