 Open Shortest Path First ( OSPF ) is one of the most widely used interior gateway protocols (IGPs) in enterprise and service provider networks. It helps routers dynamically discover the best path to reach every destination within an autonomous system. However, one of the most important — yet often misunderstood — parts of OSPF configuration is “Network Types.” In this article, we’ll break down the different OSPF network types , their uses , benefits , limitations , requirements , and a comparison between them. Whether you’re preparing for CCNA, CCNP , or designing large-scale networks, understanding OSPF network types is critical for efficient routing and convergence. 🧩 What Are OSPF Network Types? OSPF supports several network types that define how routers communicate within a particular link or segment. Each network type affects: How Hello packets are exchanged Whether a Designated Router (DR) and Backup Designated Router (BDR) are elected What kind of adjacen...
