Creating Additional OSPF Areas

To create additional OSPF areas:

Navigate to the top of the configuration hierarchy in either the J-Web or the CLI configuration editor.
Perform the configuration tasks described in Table 70.
If you are finished configuring the router, commit the configuration.
Go on to one of the following procedures:
- To configure this Services Router as an area border router, see Configuring Area Border Routers.
- To control external route advertisement in the AS, see Configuring Stub and Not-So-Stubby Areas (Optional).
- To configure an OSPF demand circuit, see Configuring Dial-on-Demand Routing with OSPF Support (Optional). (You must have already configured an ISDN interface as described in Configuring ISDN.)
- To improve network operation, see Tuning an OSPF Network for Efficient Operation.
- To check the configuration, see Verifying an OSPF Configuration.

Task	J-Web Configuration Editor	CLI Configuration Editor
Navigate to the Ospf level in the configuration hierarchy.	In the configuration editor hierarchy, select Protocols>Ospf.	From the top of the configuration hierarchy, enter edit protocols ospf
Create the additional area with a unique area ID, in dotted decimal notation—for example, 0.0.0.2.	In the Area box, click Add new entry. In the Area ID box, type 0.0.0.2.	Set the area ID to 0.0.0.2 and add an interface: set area 0.0.0.2 interface fe-0/0/0 Repeat Step 1 for each interface on this Services Router that you are adding to the area. Only one interface is required.
Add interfaces as needed to the OSPF area—for example, fe-0/0/0.	In the Interface box, click Add new entry. In the Interface name box, type fe-0/0/0. Click OK. Repeat Step 1 through Step 3 for each interface on this Services Router that you are adding to the backbone area. Only one interface is required.
