State of a neighbor, which can be:
z INCMP: Address resolution is in progress, so the link layer address of the
neighbor is unknown yet.
z REACH: The neighbor is reachable.
z STALE: The reachability to the neighbor is unknown. The device does not
verify the reachability to the neighbor unless it sends a packet to the
neighbor.
z DELAY: The reachability to the neighbor is unknown. The device will send a
neighbor request message after a delay time.
z PROBE: The reachability to the neighbor is unknown. The device sent a
neighbor request message to verify the reachability.
T
Type of neighbor information, including S (static configuration) and D (dynamic
acquisition).
Age
z For a static entry, “-“ is displayed.
z For a dynamic entry, the time (in seconds) since it is reachable last time is
displayed, and if it is never reachable, “#” is displayed (for a dynamic
neighbor only).
