Scenario 4-1: Configuring OSPF with Multiple Areas
In this scenario, you configure an eight-router, three-area network with OSPF. Figure 4-4 displays the OSPF topology and area assignment.
Figure 4-4. OSPF Topology and Area Assignment
This scenario represents a typical OSPF network with semi-redundancy and a hierarchical address assignment. To simulate a large network environment, you configure several loopback address assignments on R1 and R2.
