Usage guidelines
Perform this command to minimize link-local ND entries assigned to the driver. Link-local ND entries refer
to ND entries comprising link-local addresses.
By default, the device assigns all ND entries to the driver. With this feature enabled, the device does not
add newly learned link-local ND entries whose link local addresses are not the next hop of any route to
the driver, saving driver resources.
This feature affects only newly learned link-local ND entries rather than existing ND entries.

Parameters
aging-time: Specifies the age timer for ND entries in stale state, in the range of 1 to 1440 minutes.
Usage guidelines
ND entries in stale state have an age timer. If an ND entry in stale state is not refreshed before the timer
expires, it moves to the delay state. If it is still not refreshed in 5 seconds, the ND entry moves to the probe
state, and the device sends an NS message for detection for a maximum of three times. If no response is
received, the device deletes the ND entry.
