IV. Configure the NS Interval
After a device sends an NS message, if it does not receive a response within a specific
period, the device will send another NS message. You can configure the interval for
sending NS messages.

V. Configure the neighbor reachable timeout time on an interface
After a neighbor passed the reachability detection, the device considers the neighbor to
be reachable in a specific period. However, the device will examine whether the
neighbor is reachable again when there is a need to send packets to the neighbor after
the neighbor reachable timeout time elapsed.
