ospf_monitor(8)ospf_monitor(8)NAMEospf_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 authentication key
(if authentication is activated by the destination). Since authentica‐
tion 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 '[ # ] 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
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_com‐
mand 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 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 net‐
work'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 net‐
work'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 advertise‐
ments. 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 calcula‐
tion. 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 ta‐
ble 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. Displays the OSPF routing table. This ta‐
ble 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, neigh‐
bor IP address, state, and mode. Displays gated version information.
