             Basic BGP Convergence Benchmarking Methodology
                       for Data-Plane Convergence

Abstract

   BGP is widely deployed and used by several service providers as the
   default inter-AS (Autonomous System) routing protocol.  It is of
   utmost importance to ensure that when a BGP peer or a downstream link
   of a BGP peer fails, the alternate paths are rapidly used and routes
   via these alternate paths are installed.  This document provides the
   basic BGP benchmarking methodology using existing BGP convergence
   terminology as defined in RFC 4098.
