         YANG Data Model for OSPF SR (Segment Routing) Protocol
                       draft-ietf-ospf-sr-yang-10

Abstract

   This document defines a YANG data model that can be used to configure
   and manage OSPF Segment Routing.  The model is based on YANG 1.1 as
   defined in RFC 7950 and conforms to the Network Management Datastore
   Architecture (NDMA) as described in RFC 8342.

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.

   The YANG modules in this document conform to the Network Management
   Datastore Architecture (NMDA) [RFC8342].

   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
