Cisco routers are everywhere that networks are. They come in all sizes, from inexpensive units for homes and small offices to equipment costing well over $100,000 and capable of routing at gigabit speeds. A fixture in today's networks, Cisco claims roughly 70% of the router market, producing high-end switches, hubs, and other network hardware. One unifying thread runs through the product line: virtually all of Cisco's products run the Internetwork Operating System, or IOS. If you work with Cisco routers, it's likely that you deal with Cisco's IOS software--an extremely powerful and complex operating system, with an equally complex configuration language. With a cryptic command-line interface and thousands of commands--some of which mean different things in different situations--it doesn't have a reputation for being user-friendly. Fortunately, there's help. This second edition of Cisco IOS in a Nutshell consolidates the most important commands and features of IOS into a single, well-organized volume that you'll find refreshingly user-friendly. This handy, two-part reference covers IOS configuration for the TCP/IP protocol family. The first section includes chapters on the user interface, configuring lines and interfaces, access lists, routing protocols, and dial-on-demand routing and security. A brief, example-filled tutorial shows you how to accomplish common tasks. The second part is a classic O'Reilly quick reference to all the commands for working with TCP/IP and the lower-level protocols on which it relies. Brief descriptions and lists of options help you zero in on the commands you for the task at hand. Updated to cover Cisco IOS Software Major Release 12.3, this second edition includes lots of examples of the most common configuration steps for the routers themselves. It's a timely guide that any network administrator will come to rely on.

Pv6 Essentials discusses all aspects of IPv6, the protocol that will be used increasingly in our IP-based networks. IPv4, probably the most important networking standard in use, is growing old. It was developed almost 30 years ago and isn't able to cope with the requirements of tomorrow's networks. IPv6 is the evolution of IPv4. The two protocols are expected to coexist in our networks for many years to come. Many interoperability and transition mechanisms have been developed to ensure a smooth transition. Topics covered in this book include : The IPv6 header, Extension headers, and everything you need to know about the extended 128-bit address format ; ICMPv6 and its functions, such as neighbor and router discovery, autoconfiguration, Path MTU discovery, and multicast group management ; Security elements available in IPv6 and the IPSEC framework ; Description of QoS elements available in IPv6, including different QoS architectures ; Designs of sample networks and an overview of Mobile IPv6 ; Routing protocols such as RIPng, OSPFv3, BGP, and IS-IS. DHCP, DNS, SLP, HTTP, and other upper-layer protocols for IPv6. Interoperability and transition mechanisms and scenarios. Quick-start guide to using IPv6 on different operating systems, such as Sun Solaris, Linux, and Windows, and on routers IPv6 Essentials offers a well-organized introduction to IPv6 for experienced network professionals, as well as for administrators, managers, and executives. It explains the new features and functions of IPv6 and shows the protocol in action, including packet trace files. The book also provides an overview of where the market is, how to register IPv6 address space, and how to get started. Even if you don't plan to roll out IPv6 tomorrow, this book will help you to determine the right moment to integrate it into your corporate network strategy.

As a network administrator, auditor or architect, you know the importance of securing your network and finding security solutions you can implement quickly. This succinct book departs from other security literature by focusing exclusively on ways to secure Cisco routers, rather than the entire network. The rational is simple: If the router protecting a network is exposed to hackers, then so is the network behind it. Hardening Cisco Routers is a reference for protecting the protectors. Included are the following topics: The importance of router security and where routers fit into an overall security plan Different router configurations for various versions of Cisco?s IOS Standard ways to access a Cisco router and the security implications of each Password and privilege levels in Cisco routers Authentication, Authorization, and Accounting (AAA) control Router warning banner use (as recommended by the FBI) Unnecessary protocols and services commonly run on Cisco routers SNMP security Anti-spoofing Protocol security for RIP, OSPF, EIGRP, NTP, and BGP Logging violations Incident response Physical security Written by Thomas Akin, an experienced Certified Information Systems Security Professional (CISSP) and Certified Cisco Academic Instructor (CCAI), the book is well organized, emphasizing practicality and a hands-on approach. At the end of each chapter, Akin includes a Checklist that summarizes the hardening techniques discussed in the chapter. The Checklists help you double-check the configurations you have been instructed to make, and serve as quick references for future security procedures. Concise and to the point, Hardening Cisco Routers supplies you with all the tools necessary to turn a potential vulnerability into a strength. In an area that is otherwise poorly documented, this is the one book that will help you make your Cisco routers rock solid.
