Parameters

address ipv6-address: Displays binding information for the specified IPv6 address. If you do not specify an IPv6 address, this command displays binding information for all IPv6 addresses.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command displays binding information about IPv6 addresses for the public network.

pool pool-name: Displays IPv6 address binding information for the DHCPv6 address pool specified by its name, a case-insensitive string of 1 to 63 characters. If you do not specify a DHCPv6 address pool, this command displays IPv6 address binding information for all DHCPv6 address pools.

Table 65: Command output

Field	Description
Pool	DHCPv6 address pool.
IPv6 address	IPv6 address assigned.
Type	IPv6 address binding types: Static(F)—Free static binding whose IPv6 address has not been assigned. Static(O)—Offered static binding whose IPv6 address has been selected and sent by the DHCPv6 server in a DHCPv6-OFFER packet to the client. Static(C)—Committed static binding whose IPv6 address has been assigned to the client. Auto(O)—Offered dynamic binding whose IPv6 address has been dynamically selected by the DHCPv6 server and sent in a DHCPv6-OFFER packet to the DHCPv6 client. Auto(C)—Committed dynamic binding whose IPv6 address has been dynamically assigned to the DHCPv6 client. Auto(Z)—Zombie dynamic binding whose IPv6 address has been dynamically assigned to the DHCPv6 client. The binding becomes zombie because the subnet prefix goes invalid for address allocation after a configuration recovery, for example, after a switchover from the backup to the master.
Lease-expiration	Time when the lease of the IPv6 address will expire. If the lease expires after the year 2100, this field displays Expires after 2100. For an unassigned static binding, this field displays Not available.
Client	IPv6 address of the DHCPv6 client. For an unassigned static binding, this field is blank.
DUID	Client DUID.
IAID	Client IAID. For an unassigned static binding without IAID specified, this field displays N/A.
Preferred lifetime	Preferred lifetime in seconds of the IPv6 address.
valid lifetime	Valid lifetime in seconds of the IPv6 address.
Expires at	Time when the lease of an IPv6 address will expire. If the lease expires after the year 2100, this field displays Expires after 2100.
