OSPF Network Design Solutions, Second Edition

Case Study: OSPF Initialization

This case study puts all the pieces together into a coherent overview of OSPF initialization and beginning operation. To do this, you take a pair of routers that are connected together via an Ethernet connection to form the OSPF backbone, Area 0. Each router is also connected to other OSPF areas, as shown in Figure 3-28. For brevity, only those packets that prove a concept or step are included.

Note

To capture everything needed to demonstrate this case study, the routers were correctly configured and then a reboot was performed while a sniffer was running.
