Command Mode Interface Configuration (VLAN, Tunnel) mode User Guidelines This feature requires the IPv6 DHCP service. Enable the IPv6 DHCP service using the service dhcpv6 command. The ipv6 dhcp server command enables DHCP for IPv6 service on a specified interface using the pool for prefix delegation and other configuration through that interface. The rapid-commit keyword enables the use of the two-message exchange for prefix delegation and other configuration. If a client has included a rapid commit option in the solicit message and the rapid-commit keyword is enabled for the server, the server responds to the solicit message with a reply message. If the preference keyword is configured with a value other than 0, the server adds a preference option to carry the preference value for the advertise messages. This action affects the selection of a server by the client. Any advertise message that does not include a preference option is considered to have a preference value of 0. If the client receives an advertise message that includes a preference option with a preference value of 255, the client immediately sends a request message to the server from which the advertise message was received. The DHCP for IPv6 client, server, and relay functions are mutually exclusive on an interface. When one of these functions is already enabled and a user tries to configure a different function on the same interface, a message is displayed.
