Configuring DHCPv6 client

Overview

Serving as a DHCPv6 client, the device only supports 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.

Configuring the DHCPv6 client

Configuration prerequisites

To make the DHCPv6 client successfully obtain configuration parameters through stateless DHCPv6
configuration, make sure that the DHCPv6 server is available.

Configuration guidelines

• For more information about the ipv6 address auto command, see the Layer 3—IP Services
Command Reference.
HP does not recommend enabling the DHCPv6 client and DHCPv6 server, or the DHCPv6 client
•
and DHCPv6 relay agent on the same interface at the same time.

Configuration procedure

To configure the DHCPv6 client:
Step
1. Enter system view.
2. Enable the IPv6 packet forwarding function.
3. Enter interface view.
4. Enable IPv6 stateless address autoconfiguration.

Setting the DSCP value for DHCPv6 packets

An IPv6 packet header contains an 8-bit Traffic class field. This field identifies the service type of IPv6
packets. As defined in RFC 2474, the first six bits set the Differentiated Services Code Point (DSCP) value,
and the last two bits are reserved. Network devices use the DSCP value as a reference to determine the
packet priority for transmission.
