Are you looking for a textbook for a college networking course? If you are, then this book is for you! Author Wendell Odom, has done an outstanding job of writing a book that aims to strike a balance between theoretical knowledge and practical skills that are useful in the marketplace.
Author Odom, begins by providing detailed coverage of OSI and related terminology.
Then, the author describes the basics of how to create LANs today. He also points out the similarities between LAN and WAN, and provides details about the differences. He continues by listing the key facts about classified IP networks and explains how to discover these facts. Then, the author reviews some details of how Internet Protocol (IP) and the rest of TCP/IP’s network layer implement routing and addressing. He then focuses on IP routing, and therefore focuses on functions that match the lower three OSI layers. Next, the author explains the details of how to access a Cisco router’s user interface, how to use commands to find out how the router is currently working, and how to configure the router to tell it what to do. He also examines the design process and concepts as if you were designing a new network with no preexisting network. The author continues by focusing on the numbers and converting between the three different numbering formats, so that you can work with the masks without the math getting in the way. Then, he examines the process of breaking the subnet addresses into the three parts (network, subnet and host), based on the class and the subnet mask, along with the additional facts that can the be calculated based on that information. Next, the author examines a variety of configuration settings that can be done on a router. He also reviews the IP routing process, by which hosts and routers deliver packets from the source host to the destination host. The author continues by discussing the concepts and math to take a known IP address and mask and then fully describes a subnet by finding the values in this list. Then, he introduces the basic concepts of how routers dynamically fill their routing tables with routes using routing protocols. Next, the author shows you how some hints and tips to consider when troubleshooting a problem related to IP. He also examines some of the key concepts behind how EIGRP does its work The author continues by examining the choice of the subnet mask in more depth. Then, he looks at network ID and one subnet mask, and shows you how to calculate all the subnet IDs for all the subnets that exist in that network when using that one mask. Next, the author discusses three related topics: Variable-length subnet masks (VLSM), manual route summarization, and automatic route summarization. He also reviews concepts, by showing a suggested process for troubleshooting routing problems; as well as, examples of how to use the process. The author continues by explaining the most commonly used IP kink-state routing protocol—Open Shortest Path First. Then, he wraps up the coverage of the IPv4 control pane (the process of filling routers’ routing tables with good routes), by examining how to troubleshoot problems with Open Shortest Path First (OSPF) and Enhanced Interior Gateway Routing Protocol (EIGRP). Next, the author covers the basics of IPv6, ending with some discussions about the issues of living in a world in which both IPv4 and IPv6, will likely coexist for quite a long time. Finally, he shows you how to configure the required and optional Frame Relay features, with basic verification of each feature.
This most excellent book focuses on how to install and configure IP routers and switches. More importantly, this great book serves as a textbook for a variety of graduate and undergraduate networking courses.
