Use the following procedure to configure OSPF support as shown in Figure 55 :
1. Configure IP interfaces on each network that will be attached to OSPF areas.
In this example, two IP interfaces are needed: one for the backbone network on 10.10.7.0/24
and one for the transit area network on 10.10.12.0/24.
2. Enable OSPF.
3. Define the stub area.
4. Attach the network interface to the backbone.
5. Attach the network interface to the stub area.
6. Apply the configuration changes.
