OSPF Part 2: Using OSPF in Hierarchical Systems
This tutorial focuses on Open Shortest Path First (OSPF) in a hierarchical system. A separate tutorial (OSPF Part I) deals with using OSPF in a single area.
OSPF is a modern interior routing protocol, which uses a link state algorithm for its single-area routing. The OSPF dynamic interior routing protocol is faster, more accurate, and more scalable than its predecessors, RIPv1 and IGRP. Especially with respect to scaling, however, many of its strengths do not show up until large numbers of routers, in a hierarchy of areas, are involved. With small networks, the benefits of OSPF include fast convergence, multivendor compatibility, and CIDR/VLSM support.
