DGS-6604 ipv6 dhcp client pd 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 Syntax Description PREFIX-NAME IPv6 general prefix name. The prefix name will be associated with general prefixname 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 rapidcommit option will be filled in the Solicit message to request two message handshaking. Default Command Mode Usage Guideline The prefix delegation is disabled. Interface configuration 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 request 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.
