ospfd - an OSPFv2 routing engine for use with Quagga routing software.


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


   ospfd is a routing component that works with the Quagga routing engine.


   Options available for the ospfd command:

   -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/ospfd.conf.

   -g, --group group
          Specify the group to run as. Default is quagga.

   -h, --help
          A brief message.

   -i, --pid_file pid-file
          When ospfd starts its process identifier is written to pid-file.
          The init system uses the recorded PID to stop or restart  ospfd.
          The likely default is /var/run/ospfd.pid.

   -P, --vty_port port-number
          Specify  the  port  that  the  ospfd  VTY  will  listen on. This
          defaults to 2604, as specified in /etc/services.

   -A, --vty_addr vty-address
          Specify the address that the ospfd VTY will listen  on.  Default
          is all interfaces.

   -u, --user user
          Specify the user to run as. Default is quagga.

   -a, --apiserver
          Enable OSPF apiserver. Default is disabled.

   -v, --version
          Print the version and exit.


          The default location of the ospfd binary.

          The default location of the ospfd config file.

          If  the ospfd 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 ospfd process may log to standard output, to a VTY, to a log  file,
   or  through  syslog  to  the system logs. ospfd supports many debugging
   options, see the Info file, or the source for details.
