Totally stubby areas take this further by also filtering inter-area routes. In contrast, not-so-stubby areas (NSSA) allow the injection of external routes without the full overhead of a standard area, providing flexibility for connecting to multiple external routing domains while maintaining area efficiency.
Protocol OSPF Design Best Practices for Optimal Network Performance
This granular control allows network administrators to influence traffic engineering by adjusting reference bandwidth or manually setting interface costs to optimize flow across redundant links. Because every router shares this identical database, they can independently calculate the shortest path to any destination using Dijkstra’s algorithm, ensuring loop-free routing and a holistic view of the network infrastructure.
To ensure the integrity of the link-state database, OSPF supports authentication mechanisms, allowing administrators to configure plain text or MD5 authentication between neighbors. An OSPF network is typically divided into a backbone area (Area 0) and multiple non-backbone areas.

These adjacencies are the foundation for the reliable flooding of LSAs, ensuring that routing information is exchanged accurately and consistently between designated routers and their backups in multi-access environments. Practical Implementation and Configuration Considerations.
