        Support for Adj-RIB-Out in BGP Monitoring Protocol (BMP)
                   draft-ietf-grow-bmp-adj-rib-out-00

Abstract

   The BGP Monitoring Protocol (BMP) defines access to only the Adj-RIB-
   In Routing Information Bases (RIBs).  This document updates the BGP
   Monitoring Protocol (BMP) RFC 7854 by adding access to the Adj-RIB-
   Out RIBs.  It adds a new flag to the peer header to distinguish Adj-
   RIB-In and Adj-RIB-Out.

1.  Introduction

   BGP Monitoring Protocol (BMP) defines monitoring of the received
   (e.g.  Adj-RIB-In) Routing Information Bases (RIBs) per peer.  The
   Adj-RIB-In pre-policy conveys to a BMP receiver all RIB data before
   any policy has been applied.  The Adj-RIB-In post-policy conveys to a
   BMP receiver all RIB data after policy filters and/or modifications
   have been applied.  An example of pre-policy verses post-policy is
   when an inbound policy applies attribute modification or filters.
   Pre-policy would contain information prior to the inbound policy
   changes or filters of data.  Post policy would convey the changed
   data or would not contain the filtered data.
