NAME

       ospf_monitor - Monitors OSPF gateways

SYNOPSIS

       /usr/sbin/ospf_monitor mon_db_file

DESCRIPTION

       The  ospf_monitor  command  enables  you to query OSPF routers to obtain 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.  The ospf_monitor  command  operates
       in interactive mode.

       The  Mon_db_file 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 host name, and an  OSPF  authentica-
       tion  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 the of ospf_monitor's interactive commands.  Interactive commands can be  interrupted
       at any time by a keyboard interrupt.  Note that the command line length must be less than 200 characters.

   Local Commands
       Displays  all local commands and their functions.  Displays all remote commands and their functions.  Displays 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.   Displays	the  command  history  buffer  showing	the  last 30 interactive commands.  Exits the ospf_monitor program.  Sends
       remote_command to the same (previous) destination.  Sends remote_command to configured destination dest_index.  Sends all ospf_monitor out-
       put to filename.  Sends all ospf_monitor output to stdout.

   Remote Commands
       Displays  link  state advertisement.  The OSPF area for which the query is directed.  Specifies the one of the following type of advertise-
       ment to request: Requests 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.  Requests 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.  Requests 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.  Requests 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.  Requests 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.  The router-id of  the
       router  that  originated  this  link  state advertisement.  Displays 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.  Displays cumulative errors.	 This  log
       reports the various error conditions which can occur between OSPF routing neighbors and shows the number of occurrences for each.  Displays
       the next hop list.  This is a list of valid next hops mostly derived from the SPF calculation.  Displays 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.	Displays 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 neigh-
       bors held by this lsdb structure will be printed.  Displays 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: Routes to AS border routers in
       this area.  Routes to area border routers for this area.  Summary routes to AS border routers in other areas.  Routes to networks  in  this
       area.   Summary routes to networks in other areas.  AS routes to non-OSPF networks.  Displays all interfaces.  This report shows all inter-
       faces 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.  Displays all OSPF routing neighbors.  Information reported includes the area, local
       interface address, router ID, neighbor IP address, state, and mode.  Displays gated version information.
