Introduction to Shortest Path First Protocol (SPF)
The shortest path first protocol, or Link-state routing protocol, uses Edsger Dijkstra’s shortest path first (SPF) algorithm. Open Shortest Path First (OSPF) and Intermediate System-to-Intermediate System (IS-IS) are commonly used link-state routing protocols. Link-state routing protocols are more complex than the distance vector routing protocol. However, their basic functionality and configuration are just a sample.… Read more
