Use this command to enable the Dynamic Host Configuration Protocol (DHCP) for IPv6 client process (if the process is not currently running) and to enable requests for prefix delegation through a specified interface. 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 automatic argument.
The Prefix Delegation client is supported on only one IP interface.
rapid-commit enables the use of a two-message exchange method for prefix delegation and other configuration. If enabled, the client includes the rapid commit option in a solicit message.
The DHCP for IPv6 client, server, and relay functions are mutually exclusive on an interface. If one of these functions is already enabled and a user tries to configure a different function on the same interface, a message is displayed.
| Default | Prefix delegation is disabled on an interface. |
| Format | ipv6 dhcp client pd [rapid-commit] |
| Mode | Interface Config |
Example: The following examples enable prefix delegation on interface 1/0/1:
(Switch) #configure (Switch) (Config)#interface 1/0/1 (Switch) (Interface 1/0/1)# ipv6 dhcp client pd (Switch) #configure (Switch) (Config)#interface 1/0/1 (Switch) (Interface 1/0/1)# ipv6 dhcp client pd rapid-commit
