NAME

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

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

   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
          trouble.

          Solution is to increase receive buffer of netlink  socket.  Note
          that  kernel  <  2.6.14  doesn't  allow  increasing  it over the
          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.

FILES

   /usr/local/sbin/zebra
          The default location of the zebra binary.

   /usr/local/etc/zebra.conf
          The default location of the zebra config file.

   $(PWD)/zebra.log
          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
          zebra.

WARNING

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

DIAGNOSTICS

   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.
