YANG Data Model for Segment Routing
draft-ietf-spring-sr-yang-00
Abstract
This document defines a YANG data model ([RFC6020]) for segment
routing ([I-D.ietf-spring-segment-routing]) configuration and
operation. This YANG model is intended to be used on network
elements to configure or operate segment routing. This document
defines also generic containers that SHOULD be reused by IGP protocol
modules to support segment routing.
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].
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute

1. Introduction
This document defines a YANG data model for segment routing
configuration and operation. This document does not define the IGP
extensions to support segment routing but defines generic groupings
that SHOULD be reused by IGP extension modules. The reason of this
design choice is to not require implementations to support all IGP
extensions. For example, an implementation may support IS-IS
extension but not OSPF.
