With DHCP client enabled, an interface uses DHCP to obtain configuration parameters such as an IPv6

address, an IPv6 prefix from the DHCP server.

A DHCPv6 client can use DHCPv6 to complete the following:

• Obtain an IPv6 address and configuration parameters, and create a DHCPv6 option group for the

parameters.

• Obtain an IPv6 prefix and configuration parameters, and create a DHCPv6 option group for the

parameters.

• Support stateless DHCPv6 configuration, that is, the device can only obtain other network

configuration parameters, except the IPv6 address and prefix from the DHCPv6 server. With an

IPv6 address obtained through stateless address autoconfiguration, the device automatically

enables the stateless DHCPv6 function after it receives an RA message with the M flag set to 0 and

the O flag set to 1.

Configuration guidelines

• To make the DHCPv6 client successfully obtain IPv6 address, IPv6 prefix, and configuration

parameters through DHCPv6, make sure the DHCPv6 server is available.

• Use the ipv6 command to enable IPv6 on the DHCPv6 client. For more information about the

command, see Network Management Command Reference.

• Do not enable the DHCPv6 client and DHCPv6 server, or the DHCPv6 client and DHCPv6 relay

agent on the same interface.
