The Global Console presents the topology information in a variety of dynamically updated formats that show the status of the OSPF and physical-transport objects and their many relationships. One of those formats is the topology map, which is a graphical representation of the topology.
Viewing topology maps is an easy and quick way to learn more about the source, impact, and cause of OSPF notifications. You view the OSPF topology maps, such as the one shown in OSPF topology map, by using the Map Console view of the Global Console.
