Abstract

   This document specifies IS-IS auto-configuration mechanisms.  The key
   components are IS-IS System ID self-generation, duplication detection
   and duplication resolution.  These mechanisms provide limited IS-IS
   functions, and so are suitable for networks where plug-and-play
   configuration is expected.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in
   [RFC2119] when they appear in ALL CAPS.  When these words are not in
   ALL CAPS (such as "should" or "Should"), they have their usual
   English meanings, and are not to be interpreted as [RFC2119] key
   words.
