              BGP YANG Model for Service Provider Networks
                      draft-ietf-idr-bgp-model-09

Abstract

   This document defines a YANG data model for configuring and managing
   BGP, including protocol, policy, and operational aspects, such as
   RIB, based on data center, carrier and content provider operational
   requirements.
