Abstract
Open Shortest Path First (OSPF) currently supports multiarea networking with two severe limitations: the multiarea topology is restricted to a two-level hierarchy, and globally optimal routing may not be achieved. An OSPF extension that overcomes these limitations is proposed by introducing a routing overlay for the dissemination of multiarea routing information. It applies to both OSPFv2 (IPv4) and OSPFv3 (IPv6) and is transparent to area-internal routers. The extension was fully implemented and tested, and the results show that the added functionality is completely achieved, at the cost of a small penalty in terms of convergence times for small networks.

期刊介绍：
IET Networks covers the fundamental developments and advancing methodologies to achieve higher performance, optimized and dependable future networks. IET Networks is particularly interested in new ideas and superior solutions to the known and arising technological development bottlenecks at all levels of networking such as topologies, protocols, routing, relaying and resource-allocation for more efficient and more reliable provision of network services. Topics include, but are not limited to: Network Architecture, Design and Planning, Network Protocol, Software, Analysis, Simulation and Experiment, Network Technologies, Applications and Services, Network Security, Operation and Management.
