Description

Never has something cried out for a cookbook quite as much as Cisco's Internetwork Operating System (IOS). IOS is powerful and flexible, but also confusing and daunting. Most tasks can be accomplished in several different ways. And you don't want to spend precious time figuring out which way is best when you're trying to solve a problem quickly.

That's what this cookbook is for. Fortunately, most router configuration tasks can be broken down into several more or less independent steps: you configure an interface, you configure a routing protocol, you set up backup links, you implement packet filters and other access control mechanisms. What you really need is a set of recipes that show you how to perform the most common tasks, so you can quickly come up with a good configuration for your site. And you need to know that these solutions work: you don't want to find yourself implementing a backup link at 2 A.M. because your main link is down and the backup link you set up when you installed the router wasn't quite right.



Thoroughly revised and expanded, Cisco IOS Cookbook, 2nd Edition, adds sections on MPLS, Security, IPv6, and IP Mobility, and presents solutions to the most common configuration problems, including:

  • Configuring interfaces of many types, from serial to ATM and Frame Relay
  • Configuring all of the common IP routing protocols (RIP, EIGRP, OSPF, and BGP)
  • Configuring authentication
  • Configuring other services, including DHCP and NTP
  • Setting up backup links, and using HSRP to configure backup routers
  • Managing the router, including SNMP and other solutions
  • Using access lists to control the traffic through the router



If you work with Cisco routers, you need a book like this to help you solve problems quickly and effectively. Even if you're experienced, the solutions and extensive explanations will give you new ideas and insights into router configuration. And if you're not experienced--if you've just been given responsibility for managing a network with Cisco routers--this book could be a job-saver.

描述




沒有什麼比思科的網絡操作系統(IOS)更需要一本烹飪書了。IOS功能強大且靈活,但也令人困惑和令人生畏。大多數任務可以用幾種不同的方式完成。當您試圖快速解決問題時,您不希望花貴重的時間弄清楚哪種方式最好。

這就是這本烹飪書的用途。幸運的是,大多數路由器配置任務可以分解為幾個相對獨立的步驟:配置接口,配置路由協議,設置備份連接,實施封包過濾和其他訪問控制機制。您真正需要的是一套食譜,向您展示如何執行最常見的任務,以便您可以快速為您的網站編寫出良好的配置。您需要知道這些解決方案有效:您不希望在凌晨2點時實施備份連接,因為您的主連接已經斷開,而您在安裝路由器時設置的備份連接不太正確。





經過全面修訂和擴展,《思科IOS烹飪書》第2版增加了MPLS、安全性、IPv6和IP移動等部分,並提供了對最常見配置問題的解決方案,包括:



  • 配置各種類型的接口,從串行到ATM和幀中繼

  • 配置所有常見的IP路由協議(RIP、EIGRP、OSPF和BGP)

  • 配置身份驗證

  • 配置其他服務,包括DHCP和NTP

  • 設置備份連接,並使用HSRP配置備份路由器

  • 管理路由器,包括SNMP和其他解決方案

  • 使用訪問列表控制通過路由器的流量






如果您使用思科路由器,您需要像這樣的一本書來幫助您快速有效地解決問題。即使您有經驗,這些解決方案和詳細的解釋也將給您帶來新的想法和對路由器配置的深入了解。如果您沒有經驗,如果您剛剛負責管理一個擁有思科路由器的網絡,這本書可能會幫助您保住工作。
