Neighbor State:
Incmp - Address resolution is being performed on the entry. A neighbor solicitation message has
been sent to the solicited-node multicast address of the target, but the corresponding neighbor
advertisement message has not yet been received.
Reach - Positive confirmation was received within the last Reachable Time milliseconds that the
forward path to the neighbor was functioning properly. While in REACH state, the device takes
no special action 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 in STALE state, the device
takes no action 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. 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 message and change the state to PROBE.
Probe - A reachability confirmation is actively sought by resending neighbor solicitation
messages every RetransTimer milliseconds until a reachability confirmation is received.
Age Updated: Time since the address was confirmed to be reachable.
