ProSafe M5300 Switch NSSA Area Configuration To display the NSSA Area Configuration page, click Routing OSPF Advanced NSSA Area Configuration. To configure an OSPF NSSA area: 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 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. • 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 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. 7. Click ADD to configure the area as a NSSA area. 8. Click DELETE to delete the NSSA area designation. The area will be returned to normal state. Routing 239
