Add an OSPF NSSA area

The OSPF not-so-stubby area (NSSA) can receive external routes (Type 7 LSAs) and
learn routes from other protocols such as RIP and forward these routes to other areas.
You can select if summary LSAs (Type 3 LSAs) can be imported into stub areas.

To add an OSPF NSSA area:

1. Launch a web browser.

2. In the address field of your web browser, enter the IP address of the switch.

If you do not know the IP address of the switch, see Log in to the main UI with a web
browser
on page 27 and the subsections.

The login page displays.

3. Click the Main UI Login button.

The main UI login page displays in a new tab.

4. Enter admin as the user name, enter your local device password, and click the Login

button.

The first time that you log in, no password is required. However, you then must
specify a local device password to use each subsequent time that you log in.

The System Information page displays.

5. Select Routing > OSPF > Advanced > NSSA Area Configuration.

The OSPF NSSA Area Configuration page displays.

6. In the Area ID field, enter an OSPF area ID.

An area ID is a 32-bit integer in dotted-decimal format that identifies the area to
which a switch interface connects.

7. From the Import Summary LSAs menu, select if summary LSAs are imported:

Enable: Summary LSAs are imported into stub areas.

Disable: Summary LSAs are not imported into stub areas.

8. The options in the Default Information Originate section of the table let you configure

the switch to advertise a default route into the NSSA when the import of summary
LSAs is disabled:

a. From the Admin Mode menu, select Enable to let the switch advertise a default

route or Disable to prevent the switch from doing so.

b. In the Metric Value field, set the metric value for the default route.

The range is from 1 to 16777214.

c. From the Metric Type menu, select the type of metric that must used in the

default route:
