A device can send NS messages to detect whether its neighbors are reachable. Therefore, you can set the NS message transmission interval to control the neighbor reachability detection frequency. Frequent sending of NS messages can immediately determine whether neighbors are reachable. It, however, degrades the performance of the device. Therefore, it is recommended that the interval not be set too short.
