               YANG Data Model for Preferred Path Routing
                       draft-qct-lsr-ppr-yang-00

Abstract

   This document defines YANG data modules for preferred path routing
   ([I-D.chunduri-lsr-isis-preferred-path-routing],
   [I-D.chunduri-lsr-ospf-preferred-path-routing]) configuration and
   operation.  The YANG modules are intended to be used on network
   elements to manage the configurations and operations of preferred
   path routing.

1.  Introduction

   This document defines YANG data modules ([RFC6020], [RFC7950]) for
   preferred path routing configuration and operation.

   There are three YANG modules defined in this document.  Module ietf-
   ppr.yang defined the protocol independent part of configuration and
   operations.  Two IGP modules are defined as ietf-isis-ppr.yang and
   ietf-ospf-ppr.yang.

1.1.  Tree diagram

   Tree diagrams used in this document follow the notation defined in
   [I-D.ietf-netmod-yang-tree-diagrams].

2.  PPR YANG Module

   This YANG module defines protocol independent part of configuration
   and operation of preferred path routing (PPR) as defined in
   ([I-D.chunduri-lsr-isis-preferred-path-routing]).
