A diploma thesis introduces possibilities of the routing protocol OSPF, basic configurations and implementation into an autonomous system. A Theoretical part shows computer networks fundamentals and divide them into several groups according to standarts. It also include a part about addressing scheme in the Internet network and the ways how to subneted networks. A practical part consists of two project, that are create in a simulation program. The first simulates classroom, all the network devices and the computers are included. The second is an exam made for student to introduce OSPF in the autonomous system. The Exam uses new type of an extension, that allow student cooperate together by solving the exam. A summary contains all technique disposed in both simulations and a web presentation.
