WebAug 20, 2012 · OSPF. Open Shortest Path First (OSPF) is a routing protocol developed for IP networks by the IGP working group of the Internet Engineering Task Force (IETF). It was derived from several research efforts, including a version of OSI's IS-IS routing protocol. OSPF has two primary characteristics: • It is an open protocol. WebOSPF (open shortest path first) is a dynamic routing protocol. It is an interior gateway protocol (IGP). Routers use it to learn routes automatically, without the need for administrative intervention. Once OSPF is enabled on a router, hello packets are sent out of each participating non-passive interface. i\u0027m a buff baby i can dance like a manWebFeb 3, 2015 · OSPF is a link-state protocol based on the open standard. At a high level, OSPF operation consists of three main elements: neighbor discovery, link-state information exchange, and best-path calculation.
