         Support for Local RIB in BGP Monitoring Protocol (BMP)
                    draft-ietf-grow-bmp-local-rib-09

Abstract

   The BGP Monitoring Protocol (BMP) defines access to various Routing
   Information Bases (RIBs).  This document updates BMP (RFC 7854) by
   adding access to the Local Routing Information Base (Loc-RIB), as
   defined in RFC 4271.  The Loc-RIB contains the routes that have been
   selected by the local BGP speaker's Decision Process.
