 NAME
      ospf_monitor - monitor OSPF (Open Shortest Path First protocol)
      gateways

 SYNOPSIS
      ospf_monitor mon_db_file

 DESCRIPTION
      Use the ospf_monitor command to query OSPF routers.  The ospf_monitor
      command operates in interactive mode.  It allows the user to query the
      various OSPF routers to provide detailed information on IO statistics,
      error logs, link-state data bases, AS external data bases, the OSPF
      routing table, configured OSPF interfaces, and OSPF neighbors.

      mon_db_file is the complete pathname of a database composed of records
      configuring destinations for ospf_monitor remote commands.  Each
      destination record is a single-line entry which lists the destination
      IP address, the destination hostname, and an OSPF authentication key
      (if authentication is activated by the destination).  Since
      authentication keys may be present in the destination records, it is
      recommended that general access to this database be restricted.

      Refer to RFC-1583 (OSPF Specification, version 2) for details about
      OSPF database and packet formats.

    COMMANDS
      Upon entering interactive mode, ospf_monitor presents this prompt:

      [ # ] dest command params >&gt&gt>

      From this prompt, you can enter any of the ospf_monitor interactive
      commands.	 Interactive commands can be interrupted at any time via a
      keyboard interrupt.  Note that the command line length must be less
      than 200 characters.

    Local Commands
      ?		Display all local commands and their functions.

      ?R	Display all remote commands and their functions.

      d		Display all configured destinations. This command displays
		dest_index, the IP address, and the hostname of all
		potential ospf_monitor command destinations configured in
		mon_db_file.

      h		Display the command history buffer showing the last 30
		interactive commands.

      x		Exit the ospf_monitor program.

      @ remote_command		    Send remote_command to the same
				    (previous) destination.

      @dest_index remote_command    Send remote_command to configured
				    destination dest_index.

      F filename     Send all ospf_monitor output to filename.

      S		     Send all ospf_monitor output to stdout.

    Remote Commands
      a area_id type ls_id adv_rtr
		Display link state advertisement.  area_id is the OSPF area
		for which the query is directed.  adv_rtr is the router-id
		of the router which originated this link state
		advertisement.	type specifies the type of advertisement to
		request and should be specified as follows:

		1    Request the router links advertisements. They describe
		     the collected states of the router's interfaces. For
		     this type of request, the ls_id field should be set to
		     the originating router's Router ID.

		2    Request the network links advertisements. They describe
		     the set of routers attached to the network. For this
		     type of request, the ls_id field should be set to the
		     IP interface address of the network's Designated
		     Router.

		3    Request the summary link advertisements describing
		     routes to networks. They describe inter-area routes,
		     and enable the condensing of routing information at
		     area borders. For this type of request, the ls_id field
		     should be set to the destination network's IP address.

		4    Request the summary link advertisements describing
		     routes to AS boundary routers. They describe inter-area
		     routes, and enable the condensing of routing
		     information at area borders. For this type of request,
		     the ls_id field should be set to the Router ID of the
		     described AS boundary router.

		5    Request the AS external link advertisements. They
		     describe routes to destinations external to the
		     Autonomous System. For this type of request, the ls_id
		     field should be set to the destination network's IP
		     address.

      c		Display cumulative log. This log includes input/output
		statistics for monitor request, hello, data base
		description, link-state request, link-state update, and

		link-state ack packets. Area statistics are provided which
		describe the total number of routing neighbors and number of
		active OSPF interfaces. Routing table statistics are
		summarized and reported as the number of intra-area routes,
		inter-area routes, and AS external data base entries.

      e		Display cumulative errors. This log reports the various
		error conditions which can occur between OSPF routing
		neighbors and shows the number of occurrences for each.

      h		Display the next hop list. This list of valid next hops is
		mostly derived from the SPF calculation.

      l [retrans]
		Display the link-state database (except for ASE's). This
		table describes the routers and networks making up the AS.
		If retrans is non-zero, the retransmit list of neighbors
		held by this lsdb structure will be printed.

      A [retrans]
		Display the AS external data base entries. This table
		reports the advertising router, forwarding address, age,
		length, sequence number, type, and metric for each AS
		external route. If retrans is non-zero, the retransmit list
		of neighbors held by this lsdb structure will be printed.

      o [which] Display the OSPF routing table. This table reports the AS
		border routes, area border routes, summary AS border routes,
		networks, summary networks, and AS external networks
		currently managed via OSPF.  If which is omitted, all of the
		above will be listed. If specified, the value of which
		(between 1 and 63) specifies that only certain tables should
		be displayed. The appropriate value is determined by adding
		up the values for the desired tables from the following
		list:

		1    Routes to AS border routers in this area.

		2    Routes to area border routers for this area.

		4    Summary routes to AS border routers in other areas.

		8    Routes to networks in this area.

		16   Summary routes to networks in other areas.

		32   AS routes to non-OSPF networks.

      I		Display all interfaces. This report shows all interfaces
		configured for OSPF. Information reported includes the area,
		interface IP address, interface type, interface state, cost,

		priority, and the IP address of the DR and BDR for the
		network.

      N		Display all OSPF routing neighbors. Information reported
		includes the area, local interface address, router ID,
		neighbor IP address, state, and mode.

      V		Display Gated version information.
