A practical handbook for OSPF network design and deployment. OSPF Network Design Solutions presents a detailed, applied look into the workings of the popular Open Shortest Path First protocol, demonstrating how to dramatically increase network performance, security, and the ease with which large-scale networks are maintained. OSPF is thoroughly explained through exhaustive coverage of network design, deployment, management, and troubleshooting. The opening chapters cover network foundations, such as IP addressing, routing, various distance vector and link state protocols, and network protocol selection. Subsequent chapters quickly delve into the details of OSPF routing and network design. Advanced design concepts such as OSPF route distribution and OSPF on-demand circuit design are also covered. Later chapters focus on implementation and troubleshooting issues, network design methodology, and configuration details for different network types and area parameters. Finally, you will learn about some established and experimental techniques designed to contend with network growth. Practical case studies support concepts presented throughout the book. *Learn the most effective OSPF network design and deployment solutions *Master OSPF routing and network design issues such as OSPF convergence, area design, route selection, and VLSM *Ensure network management and security through coverage of SNMP, MIBs, and OSPF's inherent security features *Use system logging and debugging commands to monitor and troubleshoot your network *Anticipate solutions to network growth with knowledge of router CPU utilization, OSPF Internet connections, route summarization, router additions, and network expansion with VLSM
