ARP and IPv6 Neighbor Discovery use a neighbor cache to store neighbor address resolutions. The capacity of the neighbor cache is determined by the resources and capabilities of the device platform. The neighbor cache capacity feature adds a means to specify a per-interface capacity for the neighbor cache. A neighboring device, through misconfiguration or maliciousness, can unfairly use a large number of address resolutions. This feature can help to mitigate this over-utilization.

ARP and IPv6 Neighbor Discovery use a neighbor cache to store neighbor address resolutions. The cache maintains the resolutions for an interval of time after which a refresh process begins.
