Area ID
to enter the OSPF area ID. An Area ID is a 32-bit integer in dotted decimal
format that uniquely identifies the area to which a router interface connects.
2.
Use
Import Summary LSAs
to select enable or disable. If you select enable, summary
LSAs will be imported into NSSA areas.
3.
The
Default Information Originate
area displays the default Route Information. These
options will permit a user to advertise a default route into the NSSA when Import Summary
LSAs is disabled. They can also be applied by the CLI command
area (area-id) nssa
default-info-originate
in the ip router OSPF config mode.
Use
Admin Mode
to enable or disable the default information originate. Valid values
are True or False.
Use
Metric Value
to set the Default Metric value for default information originate. The
valid range of values is 1 to 16777214.

Comparable Cost
- External Type 1 metrics that are comparable to the OSPF
metric
Non-comparable Cost
- External Type 2 metrics that are assumed to be larger
than the cost of the OSPF metric.
4.
Use
Translate Role
to select the translator role of the NSSA:
always
- Cause the router to assume the role of the translator the instant it becomes
a border router.
candidate
- Cause the router to participate in the translator election process when it
attains border router status.
5.
Use
Translate Stability Interval
to configure the translator of the NSSA. The value is the
period of time that an elected translation continues to perform its duties after it determines
that its translator status has been deposed by another router.
6.
Use
No-Redistribute Mode
to configure the NSSA ABR so that learned external routes will
not be redistributed to the NSSA.
