OSPF YANG Model Augmentations for Additional Features - Version 1
draft-ietf-lsr-ospf-yang-augmentation-v1-02
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].
