Understanding the Shortest Path First (SPF) Algorithm LiveLessons—Networking Talksexplains basic SPF calculation through a combination of bullet points and whiteboard demonstrations. The lessons also demonstrate how SPF takes into account Equal-Cost MultiPath (ECMP) and multi-access links such as Ethernet. By understanding SPF calculations, engineers can better understand and troubleshoot Link State protocols. Show and hide more
