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.
   The data model builds on top of, and augments, the data model for
   network topologies defined in
   [I-D.draft-ietf-i2rs-yang-network-topo].

   This document also shows how the model can be further refined to
   cover different Layer 3 Unicast topology types.  For this purpose,
