Table 41-6 show ipv6 neighbors - display description

Field Description

IPv6 Address

IPv6 address of neighbor

Age

The time since the address was verified as reachable (in minutes). A static entry

is indicated by the value “Permanent.”

Link-layer Addr

Physical layer MAC address.

State

The following states are used for dynamic entries:

• INCMP (Incomplete) - Address resolution is being carried out on the entry.

A neighbor solicitation message has been sent to the multicast address of the

target, but it has not yet returned a neighbor advertisement message.

• REACH (Reachable) - Positive confirmation was received within the last

ReachableTime interval that the forward path to the neighbor was functioning.

While in REACH state, the device takes no special action when sending packets

• STALE - More than the ReachableTime interval has elapsed since the last

positive confirmation was received that the forward path was functioning. While

in STALE state, the device takes no action until a packet is sent.

• DELAY - More than the ReachableTime interval has elapsed since the last

positive confirmation was received that the forward path was functioning. A

packet was sent within the last DELAY_FIRST_PROBE_TIME interval. If no

reachability confirmation is received within this interval after entering the DELAY

state, the router will send a neighbor solicitation message and change the state

to PROBE.

• PROBE - A reachability confirmation is actively sought by resending neighbor

solicitation messages every RetransTimer interval until confirmation of

reachability is received.

• ???? - Unknown state.

The following states are used for static entries:
• INCMP (Incomplete)-The interface for this entry is down.
• REACH (Reachable) - The interface for this entry is up. Reachability detection is

not applied to static entries in the IPv6 neighbor discovery cache.

VLAN

VLAN interface from which the address was reached.
