1.  Introduction

   This document introduces a YANG [RFC7950] [RFC6991] data model for
   Layer 3 network topologies, specifically Layer 3 Unicast.  The model
   allows an application to have a holistic view of the topology of a
   Layer 3 network, all contained in a single conceptual YANG datastore.
