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. This prevents 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
Default
An interface can learn a maximum of 8192 dynamic neighbor entries.

Parameters
number: Specifies the maximum number of dynamic neighbor entries that an interface can learn. The value range is 1 to 8192.
Usage guidelines
The device can dynamically acquire the link-layer address of a neighboring node through NS and NA messages and add it into the neighbor table.
When the number of dynamic neighbor entries reaches the threshold, the interface stops learning neighbor information.
Examples
# Set the maximum number of dynamic neighbor entries that VLAN-interface 100 can learn to 10.
