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  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.

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.
