This entry is compiled and applied to the scientific entry of "Science China" encyclopedia. OSPF (Open Shortest Path first Open Shortest path priority) is an internal gateway protocol (Interior Gateway Protocol, or IGP) for use in single autonomous systems (autonomous system, As) within the decision routing. is an implementation of the link state routing protocol, which is subordinate to the Internal Gateway Protocol (IGP), so it operates within the autonomous system. The famous DICKERSGA algorithm (Dijkstra) is used to calculate the shortest path tree. OSPF is divided into two versions of OSPFv2 and OSPFv3, of which OSPFv2 is used in IPV4 networks, OSPFv3 used in IPV6 networks. OSPFV2 is defined by RFC 2328, and OSPFV3 is defined by RFC 5340. OSPF is a link-state protocol compared to RIP, and rip is a distance vector protocol.
