STALE: A timeout has occurred for reachability of the neigh-
bor, and an unsolicited discovery packet has been received
from the neighbor address. If the path to the neighbor is then
used successfully, this state is restored to
REACH.
• DELAY: Indicates waiting for a response to traffic sent
recently to the neighbor address. The time period for
determining the neighbor's reachability has been extended.
• PROBE: The neighbor may not be reachable. Periodic, unicast
neighbor solicitations are being sent to verify reachability.
