Parameters
aging-time: Time for a device to keep the NDP packets it receives, in the range 5 to 255 seconds.
Description
Use the ndp timer aging command to specify the time that a device should keep the NDP packets it
received from the adjacent device.
Use the undo timer aging command to restore the default.
By default, the time that a receiving device should keep the NDP packets is 180 seconds.
Note that the time for the receiving device to hold NDP packets cannot be shorter than the interval to
send NDP packets; otherwise, the NDP table may become instable.
