–
Reachable
— 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.

Last Updated
