You can delete prefix lists that are no longer needed.


  • No resources are associated with the prefix lists that you want to delete. If the prefix lists are referenced by other resources, the prefix lists cannot be deleted. You must remove all references to the prefix lists from the resources on the configuration pages of the resources before you can delete the prefix lists.
  • If RAM users are used, the RAM users are granted permissions on prefix lists. For more information, see Grant RAM users permissions on prefix lists.
Note The prefix list feature is available only in some regions.
