Open Shortest Path First (OSPF)
The Next Platform, Wednesday, November 1,2023
Open Shortest Path First (OSPF) is an IP routing protocol that uses a mathematical algorithm to calculate the most efficient path to direct traffic on IP networks.
OSPF is an open standard and designated by the Internet Engineering Task Force (IETF) as one of several Interior Gateway Protocols (IGPs) within the family of TCP/IP protocols.
Based on link-state or shortest path first (SPF) technology, OSPF distributes routing information between routers in a single autonomous system (AS). This capability differentiates OSPF from older TCP/IP routing protocols, which were designed for less complex networks than those used today.
