1.  Overview

   YANG [RFC6020]  [RFC7950] is a data definition language used to
   define the contents of a conceptual data store that allows networked
   devices to be managed using NETCONF [RFC6241].  YANG is proving
   relevant beyond its initial confines, as bindings to other interfaces
   (e.g., ReST) and encodings other than XML (e.g., JSON) are being
   defined.  Furthermore, YANG data models can be used as the basis for
   implementation of other interfaces, such as CLI and programmatic
   APIs.

   This document defines a YANG data model that can be used to configure
   and manage OSPF Segment Routing and it is an augmentation to the OSPF
   YANG data model.

1.1.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

2.  OSPF Segment Routing

   This document defines a model for OSPF Segment Routing feature [I-D.i
   etf-ospf-segment-routing-extensions][I-D.ietf-ospf-ospfv3-segment-rou
   ting-extensions].  It is an augmentation of the OSPF base model.

   The OSPF SR YANG module requires support for the base segment routing
   module [I-D.ietf-spring-sr-yang], which defines the global segment
