You can configure DHCP options for superscopes on ISC and Kea DHCP servers. Scopes within a superscope inherit the superscope’s options, while the superscope inherits the server’s options.
When a superscope is created without a scope assigned, it will not be created on the server until a scope is added. Therefore, DHCP options cannot be configured until a scope has been added first.
Note: On Kea servers, it's possible to remove scopes from the superscope and still add
options via the API, because the superscope still exists in the Kea configuration if a
scope was added to it first.
For more instructions on how to edit scope options, refer to Editing DHCP options.
