Specifically, a Neighbor Solicitation has been sent to the solicited-node multicast address of the target, but the corresponding NeighborAdvertisement has not yet been received.• REACH (Reachable)—Positive confirmation was received within the lastReachableTime milliseconds that the forward path to the neighbor wasfunctioning properly. While REACHABLE, no special action takes place aspackets are sent.• STALE—More than ReachableTime milliseconds have elapsed since thelast positive confirmation was received that the forward path wasfunctioning properly. While stale, no action takes place until a packet issent.• DELAY—More than ReachableTime milliseconds have elapsed since thelast positive confirmation was received that the forward path wasfunctioning properly, and a packet was sent within the lastDELAY_FIRST_PROBE_TIME seconds. If no reachability confirmation isreceived within DELAY_FIRST_PROBE_TIME seconds of entering theDELAY state, send a Neighbor Solicitation and change the state toPROBE.• PROBE—A reachability confirmation is actively sought by retransmittingNeighbor Solicitations every RetransTimer milliseconds until areachability confirmation is received.ExampleConsole# show ipv6 neighbors dynamicInterface IPv6 address HW address State Router---------- ----------------------- ---------------- ------ ------VLAN 1 fe80::200:cff:fe4a:dfa8 00:00:0c:4a:df:a8 stale yesVLAN 1 fe80::2d0:b7ff:fea1:264d 00:d0:b7:a1:26:4d stale noclear ipv6 neighborsUse the clear ipv6 neighbors Privileged EXEC mode command to delete allentries in the IPv6 neighbor discovery cache, except for static entries.
