1.  Introduction

   Multicast scopes are defined in [RFC4291].  [RFC7346] extends the
   scope definition with this text:

   "Interface-Local, Link-Local, and Realm-Local scope boundaries are
   automatically derived from physical connectivity or other
   non-multicast-related configurations.  Global scope has no boundary.
   The boundaries of all other non-reserved scopes of Admin-Local or
   larger are administratively configured."

   The Admin-Local scope must therefore be administratively configured.
   In this document, "administratively configured" does not imply
   actions by a human beyond installing the protocol specified herein.
   "Administratively configured" means an automatic derivation as
   described in this document.
