Configuring the DHCPv6 client
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.
Configuration guidelines
To make the DHCPv6 client successfully obtain configuration parameters through stateless DHCPv6
configuration, make sure the DHCPv6 server is available.
Do not enable the DHCPv6 client and DHCPv6 server, or the DHCPv6 client and DHCPv6 relay agent on
the same interface at the same time.
