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...
