bgpdump - translate MRT format files into readable output

       bgpdump was originally written by Dan Ardelean and the RIPE NCC took over maintenance in 2005.

       bgpdump is Copyright (C) 2007-2011 RIPE NCC

       This manpage is based on bgpdump's usage output, the  bgpdump's  homepage,  and  other  sources.  It  was
       written  for  the  Debian  project by Christoph Biedl <debian.axhn@manchmal.in-ulm.de> but may be used by
       others.

       If  a  single  update  message  contains more than 8192 added or withdrawn prefixes, all those above that
       number are ignored.

       Files with a name longer than 999 characters cannot be processed.

       The bgpdump program is not y2038 compliant. This is inherited from the file format.

       Besides bug fixes, the following changes were done in the packaging for the Debian distribution:

       •   The maximum number of prefixes processed from a single update
             messages was raised from 2050 to 8192.

       •   MRT routing table dump entries in TABLE_DUMP or TABLE_DUMP_V2 types
       •   Zebra/Quagga BGP records:
           •   BGP messages (OPEN, UPDATE, NOTIFY, KEEPALIVE)
           •   BGP state changes
       •   File may be gzipped or bzip2'd and/or passed in through stdin

       The file format is described in the Internet Draft grow-mrt-13:  <https://tools.ietf.org/html/draft-ietf-
       grow-mrt-13>
