Configuring a Single-Area OSPF Network (Required)

To use OSPF on the Services Router, you must configure at least one OSPF area, like the one shown in Figure 47.

Figure 47: Typical Single-Area OSPF Network Topology

To configure a single-area OSPF network with a backbone area, like the one in Figure 47, perform these steps on each Services Router in the network:

Navigate to the top of the configuration hierarchy in either the J-Web or CLI configuration editor.
Perform the configuration tasks described in Table 46.
If you are finished configuring the network, commit the configuration.
After you create the backbone area and add the appropriate interfaces to the area, OSPF begins sending LSAs. No additional configuration is required to enable OSPF traffic on the network.
Go on to one of the following procedures:
- To add more areas to the AS, see Configuring a Multiarea OSPF Network (Optional).
- To control external route advertisement in the AS, see Configuring Stub and Not-So-Stubby Areas (Optional).
- 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 backbone area with area ID 0.0.0.0.	In the Area box, click Add new entry. In the Area ID box, type 0.0.0.0.	Set the backbone area ID to 0.0.0.0 and add an interface. For example: set area 0.0.0.0 interface fe-0/0/0 Repeat Step 1 for each interface on this Services Router that you are adding to the backbone area. Only one interface is required. Changes in the CLI are applied automatically when you execute the set command.
Add interfaces as needed to the OSPF area.	In the Interface box, click Add new entry. In the Interface name box, type the name of an interface on the Services Router and click OK. Repeat Step 1 and Step 2 for each interface on this Services Router that you are adding to the backbone area. Only one interface is required.

Create the backbone area with area ID 0.0.0.0.

Set the backbone area ID to 0.0.0.0 and add an interface. For example:
set area 0.0.0.0 interface fe-0/0/0
Repeat Step 1 for each interface on this Services Router that you are adding to the backbone area. Only one interface is required.
Changes in the CLI are applied automatically when you execute the set command.

Add interfaces as needed to the OSPF area.

In the Interface box, click Add new entry.
In the Interface name box, type the name of an interface on the Services Router and click OK.
Repeat Step 1 and Step 2 for each interface on this Services Router that you are adding to the backbone area. Only one interface is required.
