                      draft-ietf-idr-bgp-model-03

Abstract

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

1.  Introduction

   This document describes a YANG [RFC7950] data model for the BGP
   [RFC4271] protocol, including various protocol extensions, policy
   configuration, as well as defining key operational state data.  The
   model is intended to be vendor-neutral, in order to allow operators
   to manage BGP configuration in heterogeneous environments with
   routers supplied by multiple vendors.  The model is also intended to
   be readily mapped to existing implementations to facilitate support
   from as large a set of routing hardware and software vendors as
   possible.

1.1.  Goals and approach

   The model covers the base BGP features that are deployed across major
   implementations and the common BGP configurations in use across a
   number of operator network deployments.  In particular, this model
   attempts to cover BGP features defined in BGP [RFC4271], BGP
   Communities Attribute [RFC1997], BGP Route Reflection [RFC4456],
   Multiprotocol Extensions for BGP-4 [RFC4760], Autonomous System
   Confederations for BGP [RFC5065], BGP Route Flap Damping [RFC2439],
