Parameters

ipv6-address: Specifies the IPv6 address of a neighbor whose information is displayed.

all: Displays information about all neighbors, including neighbors acquired dynamically and configured statically on the public network and all private networks.

dynamic: Displays information about all neighbors acquired dynamically.

static: Displays information about all neighbors configured statically.

slot slot-number: Specifies an IRF member device by its member ID.

interface interface-type interface-number: Specifies an interface by its type and name.

vlan vlan-id: Specifies a VLAN by its ID. The value range for VLAN ID is 1 to 4094.

verbose: Displays detailed neighbor information.

Usage guidelines

You can use the reset ipv6 neighbors command to clear IPv6 neighbor information.

Table 44: Command output

Field	Description
IPv6 Address	IPv6 address of a neighbor.
Link Layer	Link layer address (MAC address) of a neighbor.
VID	VLAN to which the interface connected with a neighbor belongs.
Interface	Interface connected with a neighbor.
State	State of a neighbor: INCMP—The address is being resolved. The link layer address of the neighbor is unknown. REACH—The neighbor is reachable. STALE—Whether the neighbor is reachable is unknown. The device does not verify the reachability any longer unless data is sent to the neighbor. DELAY—Whether the neighbor is reachable is unknown. The device sends an NS message after a delay. PROBE—Whether the neighbor is reachable is unknown. The device sends an NS message to verify the reachability of the neighbor.
Type	Neighbor information type: S—Statically configured. D—Dynamically obtained. O—Learned from the OpenFlow module. I—Invalid.
Age	A hyphen (-) indicates a static entry. For a dynamic entry, this field displays the elapsed time in seconds. If the neighbor is never reachable, this field displays a pound sign (#).
Vpn-instance	Name of a VPN or [No Vrf] with no VPN configured.
