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, and other configuration 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, management Ethernet interfaces, and VLAN interfaces.
• Do not configure the DHCPv6 client on the same interface as the DHCPv6 server or the DHCPv6
relay agent.
