Understanding Single-Area OSPF vs. Multi-Area OSPF
Open Shortest Path First (OSPF) is a link-state routing protocol widely used in enterprise IP networks for its efficiency and scalability. Unlike distance-vector protocols like RIP, OSPF uses a hierarchical design, segmenting networks into areas to optimize routing. Each area consists of routers sharing identical Link-State Databases (LSDBs), containing topology information. For CCNA and CCNP...

Introduction to Open Shortest Path First (OSPF)
Open Shortest Path First (OSPF) is a link-state routing protocol replacing the distance vector routing protocol, RIP. RIP was acceptable in the early days of networking. RIP uses hop count as the metric, which does not work better in the larger network. Open Shortest Path First (OSPF) has many advantages over RIP. It can scale...
