If you want to create identical prefix lists in multiple regions, you can use the prefix list clone feature to create identical prefix lists in multiple regions in a quick manner.


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.
