• INCMP (Incomplete)—Address resolution is being performed on the
entry. Specifically, a Neighbor Solicitation has been sent to the solicited-
node multicast address of the target, but the corresponding Neighbor
Advertisement has not yet been received.
• REACH (Reachable)—Positive confirmation was received within the last
ReachableTime milliseconds that the forward path to the neighbor was
functioning properly. While REACHABLE, no special action takes place as
packets are sent.
• STALE—More than ReachableTime milliseconds have elapsed since the
last positive confirmation was received that the forward path was
functioning properly. While stale, no action takes place until a packet is
sent.
• DELAY—More than ReachableTime milliseconds have elapsed since the
last positive confirmation was received that the forward path was
functioning properly, and a packet was sent within the last
DELAY_FIRST_PROBE_TIME seconds. If no reachability confirmation is
received within DELAY_FIRST_PROBE_TIME seconds of entering the
DELAY state, send a Neighbor Solicitation and change the state to
PROBE.
• PROBE—A reachability confirmation is actively sought by retransmitting
Neighbor Solicitations every RetransTimer milliseconds until a
reachability confirmation is received.
