Exit Overflow Interval - Enter the number of seconds that, after entering overflow state, the router
should wait before attempting to leave overflow state. This allows the router to again originate
non-default AS-external-LSAs. If you enter 0, the router will not leave Overflow State until restarted.
The range is 0 to 2147483647 seconds.

External LSDB Limit - The maximum number of AS-External-LSAs that can be stored in the
database. A value of -1 implies there is no limit on the number that can be saved. The valid range of
values is (-1 to 2147483647).

Default Metric - Sets a default for the metric of redistributed routes. This field displays the default
metric if one has already been set or blank if not configured earlier. The valid values are (1 to
16777214)

Maximum Paths - Configure the maximum number of paths that OSPFv3 can report to a given
destination. The valid values are 1 to 32.

AutoCost Reference Bandwidth - Configure the auto-cost reference-bandwidth to control how
OSPF calculates default metrics for the interface. The valid values are (1 to 4294967)

Default Passive Setting - Configure the global passive mode setting for all OSPF interfaces.
Configuring this field overwrites any present interface level passive mode setting. OSPF does not
form adjacencies on passive interfaces, but does advertise attached networks as stub networks.

Default Route Advertise

Default Information Originate - Enable or Disable Default Route Advertise. Note that the values for
'Always', 'Metric' and 'Metric Type' can only be configured after Default Information Originate is set to
enable. If Default Information Originate is set to enable and values for 'Always', 'Metric' and 'Metric
Type' are already configured, then setting Default Information Originate back to disable will set the
'Always', 'Metric' and 'Metric Type' values to default.

Always - Sets the router advertise ::/0 when set to "True".

Metric - Specifies the metric of the default route. The valid values are (0 to 16777214)

Metric Type - Sets the metric type of the default route. Valid values are External Type 1 and
External Type 2.

Non-Configurable Data

ASBR Mode - Reflects whether the ASBR mode is enabled or disabled. Enable implies that the
router is an autonomous system border router. Router automatically becomes an ASBR when it is
configured to redistribute routes learnt from other protocol.

ABR Status - The values of this are enabled or disabled. Enabled implies that the router is an area
border router. Disabled implies that it is not an area border router.

Stub Router - When OSPF runs out of resources to store the entire link state database, or any other
state information, OSPF goes into stub router mode. As a stub router, OSPF re-originates its own
router LSAs, setting the cost of all non-stub interfaces to infinity. To restore OSPF to normal
operation, disable and re-enable OSPF.

External LSDB Overflow - When the number of non-default external LSAs exceeds the configured
limit, External LSDB Limit, OSPF goes into LSDB overflow state. In this state, OSPF withdraws all of
its self-originated non-default external LSAs. After the Exit Overflow Interval, OSPF leaves the
overflow state, if the number of external LSAs has been reduced.

External LSA Count - The number of external (LS type 5) LSAs (link state advertisements) in the
link state database.

External LSA Checksum - The sum of the LS checksums of the external LSAs (link state
advertisements) contained in the link-state database. This sum can be used to determine if there has
been a change in a router's link state database, and to compare the link-state databases of two
routers.
