Abstract

   This document establishes terminology to standardize the description
   of benchmarking methodology for measuring eBGP convergence in the
   control plane of a single BGP device.  Future documents will address
   iBGP convergence, the initiation of forwarding based on converged
   control plane information and multiple interacting BGP devices.  This
   terminology is applicable to both IPv4 and IPv6.  Illustrative
   examples of each version are included where relevant.
