Open Shortest Path First (OSPF) is a link-state routing protocol that was developed for IP networks and is based on the Shortest Path First (SPF) algorithm. ... In an OSPF network, routers or systems within the same area maintain an identical link-state database that describes the topology of the area.

How does Open Shortest Path First?

Routers connect networks using the Internet Protocol (IP), and OSPF (Open Shortest Path First) is a router protocol used to find the best path for packets as they pass through a set of connected networks.

What is Shortest Path First algorithm?

What is Shortest Path First (SPF)? Also called the Dijkstra algorithm, SPF is a routing algorithm in which a router computes the shortest path between each pair of nodes in the network.
