CLI Reference Guide

ipv6 dhcp client pd
This command enables a specified IPv6 interface’s DHCP client process and it
enables the request for prefix delegation through the same interface. To disable
requests for prefix delegation, use the no form of this command.
ipv6 dhcp client pd {
PREFIX-NAME
| hint
IPV6-PREFIX
} [rapid-commit]
no ipv6 dhcp client pd
Default
The prefix delegation is disabled.
Command Mode
Interface configuration
Usage Guideline
If DHCPv6 is not running yet, executing the ipv6 dhcp client pd command starts
the DHCPv6 protocol for an IPv6 client process. Use
no ipv6 dhcp client pd
to
disable the DHCPv6 client.
Further, the
ipv6 dhcp client pd
command enables r
equest for prefix delegation
on the interface where this command is configured. When prefix delegation is
enabled and a prefix is successfully acquired, the prefix is stored in the IPv6
general prefix pool with an internal name defined by the IPV6-PREFIX argument.
Other commands and applications (such as the
ipv6 address
command) can
then refer to the prefixes in the general prefix pool.
The hint keyword with the IPV6-PREFIX argument enables the configuration of
an IPv6 prefix. That prefix will be included in DHCHv6 solicit and request
messages sent by the interface’s IPv6 client DHCP. The included prefixes, in the
messages, are sent as a hint for the prefix-delegating routers. Only one prefix
can be configured for each delegation hint request message.
Re-configuring prefix hint will change the hint setting, and setting
no ipv6 dhcp
client pd
will clear the prefix hint option. Care should be taken in setting the hint
option as it will not enable DHCPv6 client prefix delegation function.
The rapid-commit keyword enables the use of the two-message exchange
protocol for prefix delegation and other settings. If it is enabled, the client will
include the rapid commit option in a solicit message.
The DHCP for IPv6 client, server, and relay functions are mutually exclusive on
an interface.
Syntax Description
PREFIX-NAME
IPv6 general prefix name. The prefix name will be associated with general prefix-
name setting of an interface. The general prefix name can be 1-16 characters.
hint
An IPv6 prefix sent as a hint.
IPV6-PREFIX
IPv6 general prefix. It will be filled in the Solicit message to request an IPv6
prefix.
rapid-commit
(Optional) Allow two-message exchange method for prefix delegation. The rapid-
commit option will be filled in the Solicit message to request two message
handshaking.
