   OSPF YANG Model Augmentations for Additional Features - Version 1
              draft-ietf-lsr-ospf-yang-augmentation-v1-00

Abstract

   This document defines YANG data modules augmenting the IETF OSPF YANG
   model to provide support for Traffic Engineering Extensions to OSPF
   Version 3 as defined in RF 5329, OSPF Two-Part Metric as defined in
   RFC 8042, OSPF Graceful Link Shutdown as defined in RFC 8379 and OSPF
   Link-Local Signaling (LLS) Extensions for Local Interface ID
   Advertisement as defined in RFC 8510.

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 YANG data modules augmenting the IETF OSPF YANG
   model [I-D.ietf-ospf-yang], which itself augments [RFC8349], to
   provide support for configuration and operational state for the
   following OSPF features:

   RFC5329:  Traffic Engineering Extensions to OSPF Version 3 [RFC5329].

   RFC8042:  OSPF Two-Part Metric [RFC8042].

   RFC8379:  OSPF Graceful Link Shutdown [RFC8379].

   RFC8510:  OSPF Link-Local Signaling (LLS) Extensions for Local
      Interface ID Advertisement[RFC8510].

   The augmentations defined in this document requires support for the
   OSPF base model[I-D.ietf-ospf-yang] which defines basic OSPF

   configuration and state.  The OSPF YANG model augments the ietf-
   routing YANG model defined in [RFC8022].
