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.

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.
