Configuring System Information 127
• Remove — When selected, removes the neighbor from the list.
In the IPv6 Neighbors Table, the following additional parameter appears:
State — Displays the IPv6 Neighbor status. The field possible values are:
•
Incomplete — Indicates that an address resolution is in progress and the link-layer address of the
neighbor has not yet been determined.
•
Reachable — Indicates that the neighbor is known to have been reachable recently (within tens of
seconds ago).
•
Stale — Indicates that the neighbor is no longer known to be reachable but until traffic is sent to
the neighbor, no attempt is made to verify its reachability.
•
Delay — Indicates that the neighbor is no longer known to be reachable, and traffic has recently
been sent to the neighbor. Rather than probe the neighbor immediately, however, there is a delay
sending probes for a short while in order to give upper-layer protocols a chance to provide
reachability confirmation.
•
Probe — Indicates that the neighbor is no longer known to be reachable, and unicast Neighbor
Solicitation probes are being sent to verify reachability.
