IPv6 Management Features

Viewing and Clearing the IPv6 Neighbors Cache

— Continued from previous page. —

•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.
