OSPF Area Settings
This window allows the configuration of OSPF Area IDs and to designate these areas as Normal, Stub or NSSA. Normal OSPF
areas allow Link-State Database (LSDB) advertisements of routes to networks that are external to the area. Stub areas do not allow
the LSDB advertisement of external routes. Stub areas use a default summary external route (0.0.0.0 or Area 0) to reach external
destinations.
To set up an OSPF area configuration, click Layer 3 Features > OSPF > OSPF > OSPF Area Settings, as shown below:
Figure 4- 53. OSPF Area Settings window
To add an OSPF Area to the table, type a unique Area ID (see below) select the Type from the drop-down menu. For a Stub type,
choose Enabled or Disabled from the Stub Summary drop-down menu and determine the Metric. Click the Add/Modify button to
add the area ID set to the table.
To remove an Area ID configuration set, simply click
in the Delete column for the configuration.
To change an existing set in the list, type the Area ID of the set you want to change, make the changes and click the Add/Modify
button. The modified OSPF area ID will appear in the table.
