Configuring the DHCPv6 client

Overview

With DHCPv6 client configured, an interface can obtain configuration parameters from the DHCPv6
server.
A DHCPv6 client can use DHCPv6 to complete the following functions:
•
Obtain an IPv6 address, an IPv6 prefix, or both, and obtain other configuration parameters. If
DHCPv6 server is enabled on the device, the client can automatically save the obtained
parameters to a DHCPv6 option group. With the obtained IPv6 prefix, the client can generate its
global unicast address.
•
Support stateless DHCPv6 to obtain configuration parameters except IPv6 address and IPv6
prefix. The client obtains an IPv6 address through stateless IPv6 address autoconfiguration. If
the client receives an RA message with the M flag set to 0 and the O flag set to 1 during address
acquisition, stateless DHCPv6 starts.

Configuration restrictions and guidelines

When you configure DHCPv6 client, follow these restrictions and guidelines:
•
The DHCPv6 client configuration is supported only on Layer 3 Ethernet interfaces, Layer 3
aggregate interfaces, and VLAN interfaces.
•
Do not configure the DHCPv6 client on the same interface as the DHCPv6 server or the
DHCPv6 relay agent.
