ZEBRA(8)                        Version 0.97.3                        ZEBRA(8)

       zebra - a routing manager for use with associated Quagga components.

       zebra  [ -bdhklrv ] [ -f config-file ] [ -i pid-file ] [ -P port-number
       ] [ -A vty-address ] [ -u user ] [ -g group ]

       zebra is a routing manager that  implements  the  zebra  route  engine.
       zebra  supports  RIPv1,  RIPv2,  RIPng,  OSPF, OSPF6, IS-IS, BGP4+, and

       Options available for the zebra command:

       -b, --batch
              Runs in batch mode, zebra parses its config and exits.

       -d, --daemon
              Runs in daemon mode, forking and exiting from tty.

       -f, --config-file config-file
              Specifies the config file to use for startup. If  not  specified
              this option will likely default to /usr/local/etc/zebra.conf.

       -g, --group group
              Specify the group to run as. Default is quagga.

       -h, --help
              A brief message.

       -i, --pid_file pid-file
              When zebra starts its process identifier is written to pid-file.
              The init system uses the recorded PID to stop or restart  zebra.
              The likely default is /var/run/zebra.pid.

       -k, --keep_kernel
              On startup, don't delete self inserted routes.

       -P, --vty_port port-number
              Specify  the  port  that  the  zebra  VTY  will  listen on. This
              defaults to 2601, as specified in /etc/services.

       -A, --vty_addr vty-address
              Specify the address that the zebra VTY will listen  on.  Default
              is all interfaces.

       -u, --user user
              Specify the user to run as. Default is quagga.

       -r, --retain
              When the program terminates, retain routes added by zebra.

       -s, --nl-bufsize netlink-buffer-size
              Set  netlink  receive  buffer  size. There are cases where zebra
              daemon can't handle flood of netlink messages  from  kernel.  If
              you ever see "recvmsg overrun" messages in zebra log, you are in

              Solution is to increase receive buffer of netlink  socket.  Note
              that  kernel  doesn't  allow  to  increase it over maximum value
              defined in /proc/sys/net/core/rmem_max. If you want  to  do  it,
              you have to increase maximum before starting zebra.

              Note that this affects Linux only.

       -v, --version
              Print the version and exit.

              The default location of the zebra binary.

              The default location of the zebra config file.

              If  the zebra process is config'd to output logs to a file, then
              you will find this file  in  the  directory  where  you  started

       This  man  page  is  intended  to be a quick reference for command line
       options. The definitive document is the Info file Quagga.

       The zebra process may log to standard output, to a VTY, to a log  file,
       or  through  syslog  to  the system logs. zebra supports many debugging
       options, see the Info file, or the source for details.
