WebbOSPF is a dynamic routing protocol that uses Link State Routing (LSR) algorithm. It is one of the Interior Gateway Protocols (IGP) that operates within a single autonomous system. OSPF cost is its metric (the unit used by a router to make routing decisions). WebbOSPF stands for Open Shortest Path First and IS IS stands for Intermediate System to Intermediate System.. OSPF and ISIS both are routing protocols for Internet Protocol Networks. Similarities between OSPF and ISIS.
