This feature affects only newly learned link-local ND entries rather than existing ND entries.
Examples
# Minimize link-local ND entries.
<Sysname> system-view
[Sysname] ipv6 neighbor link-local minimize
ipv6 neighbor stale-aging
Use ipv6 neighbor stale-aging to set the age timer for ND entries in stale state.
Use undo ipv6 neighbor stale-aging to restore the default.
Syntax
ipv6 neighbor stale-aging aging-time
undo ipv6 neighbor stale-aging
Default
The age timer for ND entries in stale state is 240 minutes.

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.
Examples
# Set the age timer for ND entries in stale state to 120 minutes.
<Sysname> system-view
[Sysname] ipv6 neighbor stale-aging 120
ipv6 neighbors max-learning-num
Use ipv6 neighbors max-learning-num to set the maximum number of dynamic neighbor entries that an
interface can learn, to prevent the interface from occupying too many neighbor table resources.
Use undo ipv6 neighbors max-learning-num to restore the default.
Syntax
ipv6 neighbors max-learning-num number
undo ipv6 neighbors max-learning-num
