              A YANG Data Model for Routing Configuration
                    draft-ietf-netmod-routing-cfg-05

Abstract

   This document contains a specification of three YANG modules.
   Together they form the core routing data model which serves as a
   framework for configuring a routing subsystem.  It is therefore
   expected that these modules will be augmented by additional YANG
   modules defining data models for individual routing protocols and
   other related functions.  The core routing data model provides common
   building blocks for such configurations - router instances, routes,
   routing tables, routing protocols and route filters.
