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 and other configuration parameters, and automatically create a DHCPv6

option group for the obtained parameters.

• Obtain an IPv6 prefix and other configuration parameters, and automatically create a DHCPv6

option group for the obtained parameters.

• Support stateless DHCPv6. The DHCPv6 client can obtain configuration parameters except IPv6

address and IPv6 prefix. The interface obtains an IPv6 address through stateless IPv6 address

autoconfiguration. If the interface receives an RA message with the M flag set to 0 and the O flag

set to 1 during address acquisition, the interface performs stateless DHCPv6 to get other

configuration parameters.

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.
