Part II begins with a detailed explanation of how to apply the "golden rules of design" to create an optimal OSPF network and follows up with a logical approach to configuring OSPF routers and areas.
Part III provides you with detailed information about how to keep pace with network growth through tested network management tools and techniques. Furthermore, you will learn how to secure your OSPF network from inside and outside attackers and how to troubleshoot your network should problems arise. 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. Ideal for professionals who are designing, implementing or troubleshooting enterprise, dial-up, or service provider networks with EIGRP.
It details proper designs that can be used to build large and scalable EIGRP-based networks, and documents possible ways each EIGRP feature can be used in network design, implementation, troubleshooting, and monitoring. In addition you get extensive coverage of E
