Licensing Requirements and Limitations for DHCPv6

Involved Network Elements

Other network elements are not required.

Licensing Requirements

DHCPv6 requires that the device should support IPv6. The IPv6 function is controlled by a license. By default, the IPv6 function is disabled on a new device. To use the IPv6 function, apply for and purchase the license from the device supplier.
