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. The
client automatically creates a DHCPv6 option group for the obtained parameters. 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.
Do not configure the DHCPv6 client on the same interface as the DHCPv6 server or the DHCPv6
relay agent.

Remarks
N/A
Supported interfaces include
Layer 3 Ethernet interface, Layer
3 Ethernet subinterface, Layer 3
aggregate interface, Layer 3
aggregate subinterface, and
VLAN interface.
By default, the interface does not
use DHCPv6 for IPv6 address
acquisition.
