DHCP FOR IPV6 (DHCPV6) COMMANDS
PREFIX
-DELEGATION POOL
prefix-delegation pool
Overview Use this command in DHCPv6 Configuration mode to add a DHCPv6 server
prefix-delegation pool entry to the current DHCPv6 pool configuration. You must
define a DHCPv6 server prefix-delegation pool using the ipv6 dhcp pool command
before using this command.
Use the no variant of this command to remove a DHCPv6 server prefix-delegation
pool from the current DHCPv6 pool configuration.
Syntax
prefix-delegation pool <DHCPv6-poolname> [lifetime
{<valid-time>|infinite} {<preferred-time>|infinite}]
no prefix-delegation pool <DHCPv6-poolname>
Default No IPv6 local prefix pool is specified by default.
Mode DHCPv6 Configuration
Usage The DHCPv6 server assigns prefixes dynamically from an IPv6 local prefix pool,
which is configured using the ipv6 local pool command and is associated with a
DHCPv6 configuration pool using this command. When the server receives a prefix
request from a client, it attempts to obtain unassigned prefixes from the pool. After
the client releases the previously assigned prefixes, the server returns the prefixes
to the pool for reassignment.
Preferred IPv6 addresses or prefixes are available to interfaces for unrestricted use
and are deprecated when the preferred timer expires.
Deprecated IPv6 addresses and prefixes are available for use and are discouraged
but not forbidden. A deprecated address or prefix should not be used as a source
Parameter Description
<DHCPv6-poolname> Description used to identify this DHCPv6 server pool. Valid
characters are any printable character. If the name contains
spaces then you must enclose it in “quotation marks”.
lifetime Optional. Specify a time period for the hosts to remember
router advertisements (RAs). If you specify this parameter
then you must also specify a valid-time and a preferred-time
value.
See the Usage notes below this parameter table for a
description of preferred and valid lifetimes and how these
determine deprecated or invalid IPv6 addresses upon expiry.
<valid-time> Specify a valid lifetime in seconds in the range
<5-315360000>.
infinite Specify an infinite valid lifetime or an infinite preferred
lifetime, or both, when using this keyword.
<preferred-time> Specify a valid lifetime in seconds in the range
<5-315360000>.
