State

class InterfacesState.Interface.Ipv6.Neighbor.State

State (Enum Class)

incomplete = 0

Address resolution is in progress, and the link-layer

address of the neighbor has not yet been

determined.

reachable = 1

Roughly speaking, the neighbor is known to have been

reachable recently (within tens of seconds ago).

stale = 2

The neighbor is no longer known to be reachable, but

until traffic is sent to the neighbor no attempt

should be made to verify its reachability.

delay = 3

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,

delay sending probes for a short while in order to

give upper-layer protocols a chance to provide

reachability confirmation.

probe = 4

The neighbor is no longer known to be reachable, and

unicast Neighbor Solicitation probes are being sent

to verify reachability.
