         YANG Data Model for OSPF SR (Segment Routing) Protocol
                       draft-ietf-ospf-sr-yang-14

Abstract

   This document defines a YANG data module that can be used to
   configure and manage OSPF Segment Routing.  It also defines a module
   for management of Signaling Maximum SID Depth (MSD) Using OSPF.  The
   modules are based on YANG 1.1 as defined in RFC 7950 and conform 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 [RFC8665] and it is an augmentation
   to the OSPF YANG data model.

   This document also defines a YANG data model for Signaling Maximum
   SID Depth (MSD) Using OSPF [RFC8476], which augments the base OSPF
   YANG data model.
