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