radvdump - dump router advertisements


   radvdump [ -vhfe ] [ -d debuglevel ]


   radvdump prints out the contents of incoming router advertisements sent
   by radvd or some  other  software  implementing  (parts  of)  "Neighbor
   Discovery for IP Version 6 (IPv6)" (RFC 4861).


   For  every  one  character option there is also a long option, which is
   listed right next to the "short" option name:

   -v, --version
          Displays the version of radvdump and then aborts.

   -h, --help
          Displays a short usage description and then aborts.

   -f, --file-format
          Output received router advertisements in the format of the radvd
          configuration  file.   Since  radvd 0.9, this is the default and
          the switch is provided for backward compatibility only.

   -e, --exclude-defaults
          Exclude default valued options from configuration  file  format.
          This option is ignored if option -f is not set.

   -d debuglevel, --debug debuglevel
          With   this  option  you  turn  on  debugging  information.  The
          debugging level is an integer in the range from  1  to  4,  from
          quiet  to  very verbose. A debugging level of 0 completely turns
          off debugging.

          The default debugging level is 0.




   There certainly  are  some  bugs.  If  you  find  them  or  have  other
   suggestions please contact Reuben Hawkins <reubenhwk@gmail.com>.
