Cisco IP Routing: Packet Forwarding and Intra-domain Routing Protocols
As a networking professional, you will find this practical guide an invaluable resource for understanding routing technologies and configuring and troubleshooting Cisco routers, as well as for studying for the CCIE exam.  Cisco IP Routing presents the most thorough information available on the inner workings of Cisco routers.  Focusing on intra-domain dynamic routing protocols, the book provides an in-depth understanding of IP routing and forwarding technologies, and their implementation within Cisco routers.You will find essential background information on IP addressing, general routing and forwarding processes, and routing table maintenance.  The book discusses packet forwarding and static routing, and details the specific mechanisms inside the dynamic routing protocols, covering both the distance vector and link-state routing protocols.  Routing Information Protocol (RIP), Interior Gateway Routing Protocol (IGRP), Open Shortest Path First (OSPF), and  Enhanced IGRP (EIGRP), Cisco's proprietary routing protocol, are covered in depth within the context of Cisco's implementation.Specific topics covered include:Variable length subnet masksClassful and classless addressing and routingRouting and forwarding differencesStatic and dynamic routingRouting table structure and maintenance in Cisco routersCisco packet switching mechanisms, including fast, optimum, distributed, NetFlow, and Cisco Express ForwardingCisco load-sharing techniquesThe Bellman-Ford and Dijkstra algorithmsRIP packet formats, input and outbound messaging, event processing, configuration commands, and moreIGRP packet formats, input and outbound messaging, events processing, configuration commands, and moreComparison between ISIS and OSPFOSPF subprotocols and packet formatsOSPF intra-area, inter-area and external routingOSPF flooding algorithm and link-state database synchronizationLSA installation and SPF schedulingOSPF configuration and implementation in Cisco routersEIGRP operation and configurationEIGRP stub router featureNumerous examples of logs from real Cisco routers illustrate the concepts presented and their practical application.  Useful configuration examples are also presented.  In addition, many of the chapters include a Frequently Asked Questions section that clarifies common misunderstandings and confusion about IP routing technologies and Cisco routers.Comprehensive, yet detailed and accessible,Cisco IP Routingprovides the inside information you need to be a truly proficient Cisco router networking professional.0201604736B07242001
