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.

   module: ietf-isis-reverse-metric
     augment /rt:routing/rt:control-plane-protocols
               /rt:control-plane-protocol/isis:isis/isis:interfaces
               /isis:interface:

          +--rw exclude-te-metric?   boolean
