options:
  -h, --help            show this help message and exit
  --conf_dir CONF_DIR   Path to the router directory
  --config-dir DIR      Path to a config directory to pull `*.conf` files from. This file set is
                        sorted, so as to provide a predictable parse order if individual options
                        are over-ridden. The set is parsed after the file(s) specified via
                        previous --config-file, arguments hence over-ridden options in the
                        directory take precedence. This option must be set from the command-line.
  --config-file PATH    Path to a config file to use. Multiple config files can be specified, with
                        values in later files taking precedence. Defaults to None. This option
                        must be set from the command-line.
  --debug, -d           If set to true, the logging level will be set to DEBUG instead of the
                        default INFO level.
  --enable_conntrackd   Enable conntrackd support
  --group GROUP         Group (gid or name) running this process after its initialization
  --log-config-append, --log-config, --log_config PATH
                        The name of a logging configuration file. This file is appended to any
                        existing logging configuration files. For details about logging
                        configuration files, see the Python logging module documentation. Note
                        that when logging configuration files are used then all logging
                        configuration is set in the configuration file and other logging
                        configuration options are ignored (for example, log-date-format).
  --log-date-format DATE_FORMAT
                        Defines the format string for %(asctime)s in log records. Default: None .
                        This option is ignored if log_config_append is set.
  --log-dir, --logdir LOG_DIR
                        (Optional) The base directory used for relative log_file paths. This
                        option is ignored if log_config_append is set.
  --log-file, --logfile PATH
                        (Optional) Name of log file to send logging output to. If no default is
                        set, logging will go to stderr as defined by use_stderr. This option is
                        ignored if log_config_append is set.
  --monitor_cidr MONITOR_CIDR
                        CIDR to monitor
  --monitor_interface MONITOR_INTERFACE
                        Interface to monitor
  --namespace NAMESPACE
                        Namespace of the router
  --nodebug             The inverse of --debug
  --noenable_conntrackd
                        The inverse of --enable_conntrackd
  --nouse-journal       The inverse of --use-journal
  --nouse-json          The inverse of --use-json
  --nouse-syslog        The inverse of --use-syslog
  --pid_file PID_FILE   Path to PID file for this process
  --router_id ROUTER_ID
                        ID of the router
  --shell_completion SHELL_COMPLETION
                        Display a shell completion script Allowed values: bash, zsh
  --state_path STATE_PATH
                        Where to store Neutron state files. This directory must be writable by the
                        agent.
  --syslog-log-facility SYSLOG_LOG_FACILITY
                        Syslog facility to receive log lines. This option is ignored if
                        log_config_append is set.
  --use-journal         Enable journald for logging. If running in a systemd environment you may
                        wish to enable journal support. Doing so will use the journal native
                        protocol which includes structured metadata in addition to log
                        messages.This option is ignored if log_config_append is set.
  --use-json            Use JSON formatting for logging. This option is ignored if
                        log_config_append is set.
  --use-syslog          Use syslog for logging. Existing syslog format is DEPRECATED and will be
                        changed later to honor RFC5424. This option is ignored if
                        log_config_append is set.
  --user USER           User (uid or name) running this process after its initialization
  --version             show program's version number and exit
