1.  Introduction

   This document defines a YANG [RFC7950] data model for describing the
   relationship between a layer 3 network topology
   [I-D.ietf-i2rs-yang-l3-topology] and a TE topology
   [I-D.ietf-teas-yang-te-topo].

   When traffic engineering is enabled on a layer 3 network topology,
   there will be a corresponding TE topology.  The TE topology may or
   may not be congruent to the layer 3 network topology.  When such a
   congruent TE topology exists, there will be a one-to-one association
   between the one modeling element in the layer 3 topology to another
   element in the TE topology.  When such a congruent TE topology does
