ospf_monitor - Monitors OSPF gateways
/usr/sbin/ospf_monitor mon_db_file
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 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.
Upon entering interactive mode, ospf_monitor presents the
'[ # ] dest command params >' prompt, at which you can
enter any 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 [Toc] [Back]
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 output to filename.
Sends all ospf_monitor output to stdout.
Remote Commands [Toc] [Back]
Displays link state advertisement. The OSPF area for
which the query is directed. Specifies the one of the
following type of advertisement 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 nonzero,
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 nonzero,
the retransmit list of neighbors 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 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. 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.
