Parameters
interval: LAN-delay time in milliseconds, with an effective range of 1 to 32,767.
Description
Use the hello-option lan-delay command to configure the global value of the
LAN-delay time, namely the length of time the device waits between receiving a prune
message from downstream and taking the prune action. Within this period of time, if the
device receives a prune override message from that downstream device, the prune
action will be overridden.
Use the undo hello-option lan-delay command to restore the system default.
By default, the LAN-delay time is 500 milliseconds.
This command is effective for both PIM-DM and PIM-SM.
