What is a characteristic of a single-area OSPF network?
- All routers share a common forwarding database.
- All routers have the same neighbor table.
- All routers are in the backbone area.
- All routers have the same routing table.
Explanation: In a single-area OSPF implementation, all participating routers are located within one administrative area. Best practice dictates that this single area should be Area 0, also known as the backbone area. This ensures that if the network scales to a multiarea design in the future, all other areas can connect directly to this required backbone. While routers in the same area share an identical Link-State Database (topology table), their neighbor tables and routing tables (forwarding databases) are unique to each individual router based on its specific location and adjacencies.
