 Multi-Threaded Routing Toolkit (MRT) Routing Information Export Format

Abstract

   This document describes the MRT format for routing information
   export.  This format was developed in concert with the Multi-threaded
   Routing Toolkit (MRT) from whence the format takes it name.  The
   format can be used to export routing protocol messages, state
   changes, and routing information base contents.
