OSPF Beyond the Basics: An Ultimate OSPF Guide

OSPF (Open Shortest Path First) is a popular, widely-used routing protocol for Internet Protocol (IP) networks. OSPF was developed in the late 1980s as a solution to the limitations of the older Routing Information Protocol (RIP) and is widely used in enterprise networks and service provider networks.

OSPF uses a link-state routing (LSR): it works by creating a complete topological map of the network, which is then used to calculate the shortest path to a destination. This information is then distributed to all routers in the network, allowing them to make informed decisions about the best path to a destination. OSPF also supports hierarchical network design, allowing large networks to be divided into smaller, more manageable areas.
