Configuring network parameters in a DHCPv6 option group

A DHCPv6 option group can be created by using the following methods:

• Create a static DHCPv6 option group by using the ipv6 dhcp option-group command. The static DHCPv6 option group takes precedence over the dynamic DHCPv6 option group.

• When the device acts as a DHCPv6 client, it automatically creates a dynamic DHCPv6 option group for saving the obtained parameters. For more information about creating a dynamic DHCPv6 option group, see "Configuring the DHCPv6 client."
