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. During the refresh process, a number of ARP requests or IPv6 ND Neighbor Solicitations are sent to the neighbor until the neighbor either responds with an ARP reply or IPv6 ND Neighbor Advertisement.

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.
