Open Shortest Path First (OSPF) ● Autonomous Systems (AS) ● The Internet is divided into autonomous systems (AS, 32 bit ID, was 16 bit) ● Each autonomous system has a backbone, which connects all parts of the AS ● Large autonomous systems are divided into areas ● Area of an AS ● Within an area every router has the same link state database and implements the same algorithm for determination of the shortest path ● Every router, which belongs to two or more areas, is part of the backbone ● A router, which connects two areas, needs the link state databases from both areas Univ.-Prof. Dr.-Ing.

Open Shortest Path First (OSPF) ● OSPF distinguishes four router classes ● For reducing the extent of routing tables ● Classes of routers ● Internal routers, which only belong to one area ● Area routers at the border of areas, which connect two or more areas ● Backbone routers, which are placed at the backbone ● AS border routers, which mediate between several autonomous systems Univ.-Prof. Dr.-Ing.
