1. Introduction

   This document defines a YANG [RFC6020] data model for describing the
   presentations of Segment Routing (SR) topology and Segment Routing
   (SR) traffic engineering (TE) topology.

1.1. Terminology

   The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP

2. Modeling Considerations

2.1. Segment Routing (SR) topology

   The Layer 3 network topology model is discussed in [YANG-L3-TOPO].
   The Segment Routing (SR) topology model proposed in this document
   augments and uses the ietf-l3-unicast-igp-topology module defined in
   [YANG-L3-TOPO]. SR related attributes are covered in the ietf-sr-
   topology model.
