Once OSPF is initialized on the router, it will remain initialized until the router is reset.
RFC 1583 Compatibility - Select enable or disable from the pulldown menu to specify the preference
rules that will be used when choosing among multiple AS-external-LSAs advertising the same
destination. If you select enable, the preference rules will be those defined by RFC 1583. If you select
disable, the preference rules will be those defined in Section 16.4.1 of the OSPF-2 standard (RFC
2328), which will prevent routing loops when AS-external-LSAs for the same destination have been
originated from different areas. The default value is 'enable'. To prevent routing loops, you should
select 'disable', but only if all OSPF routers in the routing domain are capable of operating according
to RFC 2328.
Exit Overflow Interval (secs)- 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.
SPF DelayTime(secs) - Enter the number of seconds, Delay time (in seconds)is the time between
when OSPF receives a topology change and when it starts an SPF calculation. It can be an integer
from 0 to 65535. The default time is 5 seconds. A value of 0 means that there is no delay; that is, the
SPF calculation is started immediately.
SPF HoldTime(secs) - Enter the number of seconds, minimum time (in seconds) between two
consecutive SPF calculations.It can be an integer from 0 to 65535. The default time is 10 seconds. A
value of 0 means that there is no delay; that is, two SPF calculations can be done, one immediately
after the other.
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
16777215)
Maximum Paths - Sets the maximum number of paths that OSPF can report for a given destination.
The valid values are (1 to 6).
Default Information Originate - Enable or Disable Default Route Advertise.
Always - Sets the router advertise 0.0.0.0/0.0.0.0 when set to "True".
Metric - Specifies the metric of the default route. The valid values are (0 to 16777215)
Metric Type - Sets the metric type of the default route.
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.
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.
New LSAs Originated - In any given OSPF area, a router will originate several LSAs. Each router
originates a router-LSA. If the router is also the Designated Router for any of the area's networks, it
will originate network-LSAs for those networks. This value represents the number of LSAs originated
by this router.
