1.  Introduction

   This document defines a YANG module for managing the reverse metric
   extension to the intermediate system to intermediate system routeing
   protocol (IS-IS) [RFC8500], [ISO10589].  Please refer to [RFC8500]
   for the description and definition of the functionality managed by
   this module.

   The YANG data model described in this document conforms to the
   Network Management Datastore Architecture defined in [RFC8342].

2.  YANG Management

2.1.  YANG Tree

   The following is the YANG tree diagram ([RFC8340]) for the IS-IS
   reverse metric extension additions.
