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.
Opaque LSA Status-
Set this parameter to Enable to if OSPF should store and flood opaque LSAs.
The default value is Enable. An opaque LSA is used for flooding user-defined information within an
OSPF router domain.
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.
External LSDB Limit-
The maximum number of External LSAs that can be stored in the database.
Default value for limit is -1. A value of -1 indicates there is no limit. 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
16777215)
Maximum Paths
- Sets the maximum number of paths that OSPF can report for a given destination.
The valid values are (1 to 6).
AutoCost Reference Bandwidth-
Configure the auto-cost reference-bandwidth to control how
OSPF calculates link cost. Specify the reference bandwidth in megabits per second. Unless a link
cost is configured, the link cost is computed by dividing the reference bandwidth by the interface
bandwidth. Default value is 100. The range is (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 is Disable.
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.
Helper Support Mode-
Configures how unit will act when a neighbor performs a warm restart. The
possible values are:
Planned
- Indicates that OSPF should only help a restarting neighbor during planned events.
Always
- Indicates that OSPF help a restarting neighbor during all planned and unplanned
warm restart events.
