Configuring acquisition of configuration parameters except IP addresses and prefixes

When a DHCPv6 client has obtained an IPv6 address and prefix, you can configure the following methods for the client to obtain other network configuration parameters:

• Execute the ipv6 address auto command to enable an interface to automatically generate an IPv6 global unicast address and a link-local address. Then stateless DHCPv6 will be triggered when the M flag is set to 0 and the O flag is set to 1 in a received RA message. For more information about the commands, see Layer 3—IP services Command Reference.

• Executing the ipv6 dhcp client stateless enable command on an interface to enable the interface to act as a DHCPv6 client to obtain configuration parameters from a DHCPv6 server.

If you execute both the ip address auto and ipv6 dhcp client stateless enable commands, the interface acts as follows:

• Generate a global unicast address and a link-local address.

• Obtain other configuration parameters from a DHCPv6 server.

1. Enter system view.

   system-view

2. Enter interface view.

   interface interface-type interface-number

3. Configure the interface to support stateless DHCPv6. Choose the options to configure as needed:

   • Enable stateless IPv6 address autoconfiguration:

     ipv6 address auto

   • Configure the client to obtain network parameters from DHCPv6 servers:

     ipv6 dhcp client stateless enable

   By default, the interface does not support stateless DHCPv6.
