                        An I2RS BGP Data Modell
                     draft-hares-i2rs-bgp-dm-00.txt

Abstract

   This document introduces a yang data for i2RS BGP protocol and
   network policy that aligns with the I2RS BGP use cases.  This draft
   utilizes the general Policy based routing structured found in the RIB
   Information Model (IM) and Policy Base Policy.

1.  Introduction

   The Interface to the Routing System (I2RS) provides read and write
   access to the information and state within the routing process within
   routing elements via protocol message exchange between an I2RS Client
   and an I2RS Agent associated with the a routing system.  The
   [I-D.ietf-i2rs-architecture] describes the basic interactions of this
   exchange.  One of the important functions of this messages exchange
   is for the I2RS client to interact with one or more I2RS agents to
   collect information from network routing systems.

   One of the key information pieces that I2RS clients may collect from
   I2RS agents is the BGP information regarding BGP peers, BGP routes,
   and network topologies created within BGP.  This document introduces
   a basic information model for BGP policies.  This policy model can be
   linked with other information models such as the I2RS RIB
   informational model [I-D.ietf-i2rs-rib-info-model], and uses the
   generic policy found in the Policy Routing modules in
   [I-D.hares-i2rs-bnp-info-model].  This basic BGP Information Model is
   an extendable policy model is a product of the industry approach to
   I2RS.
