The following table describes the nonconfigurable data that is displayed.
Table 52. IPv6 Neighbor Table information
Field Description
Interface The interface whose settings are displayed in the current table row.
IPv6 Address The IPv6 address of the neighbor or interface.
MAC Address The MAC address associated with an interface.
isRtr Indicates whether the neighbor is a router. If the neighbor is a router, the value is True. If
the neighbor is not a router, the value is False.
Neighbor State The state of the neighbor cache entry. Following are the states for dynamic entries in the
IPv6 neighbor discovery cache:
• Incomplete. Address resolution is being performed on the entry. A neighbor
solicitation message was sent to the solicited-node multicast address of the target,
but the corresponding neighbor advertisement message is not yet received.
• Reachable. Positive confirmation was received within the last Reachable Time
milliseconds that the forward path to the neighbor was functioning properly. While in
REACH state, the device takes no special action as packets are sent.
• Stale. More than Reachable Time milliseconds elapsed since the last positive
confirmation was received that the forward path was functioning properly. While in
STALE state, the device takes no action until a packet is sent.
• Delay. More than Reachable Time milliseconds elapsed since the last positive
confirmation was received that the forward path was functioning properly. A packet
was sent within the last DELAY_FIRST_PROBE_TIME seconds. If no reachability
confirmation is received within DELAY_FIRST_PROBE_TIME seconds of entering
the DELAY state, send a neighbor solicitation message and change the state to
PROBE.
• Probe. Seeks a reachability confirmation by resending neighbor solicitation
messages every Retrans Timer milliseconds until a reachability confirmation is
received.
Last Updated Time since the address was confirmed to be reachable.
