ProSafe M5300 Switch NSSA Area Configuration To display the NSSA Area Configuration page, click Routing OSPFv3 Advanced  NSSA Area Configuration. 1. Use 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 areas. Defaults to Enable. 3. Use Default Information Originate to advertise a default route into the NSSA when Import Summary LSAs is disabled. This can also be applied by the CLI command area nssa default-info-originate in the IPv6 router OSPF config mode. 4. Use Admin Mode to enable or disable the default information originate. Valid values are True or False. 5. Use Metric Value to set the Default Metric value for default information originate. The valid range of values is 1 to 16777214. 6. Use Metric Type to select the type of metric specified in the Metric Value field. • Comparable Cost - External Type 1 metrics that are comparable to the OSPFv3 metric • Non-comparable Cost - External Type 2 metrics that are assumed to be larger than the cost of the OSPFv3 metric 7. Use Translator Role to specify the NSSA Border router's ability to perform NSSA translation of type-7 LSAs into type-5 LSAs. The valid values are 'Always' and 'Candidate'. 8. Use Translator Stability Interval to specify the number of seconds after an elected translator determines its services are no longer required, that it should continue to perform its translation duties. The valid range of values is 0 to 3600. 9. Use No-Redistribute Mode to enable or disable the No-Redistribute Mode. 10. Click ADD to configure the area as a NSSA area. 11. Click DELETE to delete the NSSA area designation. The area will be returned to normal state. Field SPF Runs Area Border Router Count Description The number of times that the intra-area route table has been calculated using this area's link-state database. This is done using Dijkstra's algorithm. The total number of area border routers reachable within this area. This is initially zero, and is calculated in each SPF Pass. Routing 264

.
1.
Use
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 areas. Defaults to Enable.
3.
Use
Default Information Originate
to advertise a default route into the NSSA when Import
Summary LSAs is disabled. This can also be applied by the CLI command
area
<areaid> nssa default-info-originate
in the IPv6 router OSPF config mode.
4.
Use
Admin Mode
to enable or disable the default information originate. Valid values are
True or False.
5.
Use
Metric Value
to set the Default Metric value for default information originate. The valid
range of values is 1 to 16777214.
6.
Use
Metric Type
to select the type of metric specified in the Metric Value field.
Comparable Cost
- External Type 1 metrics that are comparable to the OSPFv3
metric
Non-comparable Cost
- External Type 2 metrics that are assumed to be larger than
the cost of the OSPFv3 metric
7.
Use
Translator Role
to specify the NSSA Border router's ability to perform NSSA translation
of type-7 LSAs into type-5 LSAs. The valid values are 'Always' and 'Candidate'.
8.
Use
Translator Stability Interval
to specify the number of seconds after an elected
translator determines its services are no longer required, that it should continue to perform
its translation duties. The valid range of values is 0 to 3600.
9.
Use
No-Redistribute Mode
to enable or disable the No-Redistribute Mode.
