Options
- ANon-core regions (such as Area 1) are not directly connected to the core region (Area 0).
- BThe backbone area Area 0 is divided into two parts, requiring virtual link connections.
- CAll areas are directly connected to Area 0, requiring no virtual links.
- DUse only static routes to connect non-backbone areas; no virtual links are needed.
