        A YANG Data Model for Routing Management (NMDA Version)

Abstract

   This document specifies three YANG modules and one submodule.
   Together, they form the core routing data model that serves as a
   framework for configuring and managing a routing subsystem.  It is
   expected that these modules will be augmented by additional YANG
   modules defining data models for control-plane protocols, route
   filters, and other functions.  The core routing data model provides
   common building blocks for such extensions -- routes, Routing
   Information Bases (RIBs), and control-plane protocols.

   The YANG modules in this document conform to the Network Management
   Datastore Architecture (NMDA).  This document obsoletes RFC 8022.
