Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), …

Oct 8, 2025 · Open Shortest Path First (OSPF) is a link-state Interior Gateway Protocol (IGP) developed by the Internet Engineering Task Force (IETF) to provide efficient routing within an …

OSPF (Open Shortest Path First) is an Interior Gateway Protocol (IGP). It is a link-state routing protocol that uses the Shortest Path First (SPF) algorithm to calculate the best route.

Mar 1, 2024 · Open Shortest Path First (OSPF) is a widely used link-state dynamic routing protocol designed for medium to large IP networks. It determines the most efficient path for …

Apr 29, 2025 · OSPF (Open Shortest Path First) is one of the most widely used routing protocols in modern IP networks. Designed to efficiently direct traffic within a single autonomous system, …

This lesson explains the basics of OSPF, a link-state IGP routing protocol that builds a LSDB by exchanging LSAs.

Oct 30, 2023 · What is Open Shortest Path First (OSPF)? Open Shortest Path First (OSPF) is an IP routing protocol that uses a mathematical algorithm to calculate the most efficient path to …

Feb 23, 2025 · OSPF is a link-state routing protocol designed to work with IP networks. Unlike older distance-vector protocols like RIP, which simply count “hops,” OSPF employs an …

This lesson explains what OSPF is. We introduce some of the fundamental OSPF concepts such as RID, LSA, LSDB, Adjacencies, and Areas at a high level.
