本书是**本由Cisco Systems授权讲述CCIE实验考试的书籍。
本书主要目的是用来帮助那些CCIE备选者们通过完成许多实验来准备CCIE实验考试。这些实验是用来测试应试者在参考答案之前解决实际问题的能力。这些实验里的许多内容都是非常有难度的，如果你没有在实际环境中完成这些实验，那么在真正的CCIE考试中就有可能漏掉许多细节，从而导致整个考试的失败。本书结构遵从OSI模型及网络自低向高的构建方式。第1部分主要讲述物理层和路由器基本的设置和访问知识。第2部分“LAN模型的建立”和第3部分“采用广域网互联局域网”关注数据链路层，而第4部分“路由协议”则关注第3层和第4层的内容。第5到第６部分则分别介绍传输非路由协议、网络控制与网络访问、增强型网络协议。每一部分后面都有一个或者多个复杂的实验。第8部分讨论了现在的CCIE实验认证考试，提供了学习要点和建议以帮助应试者准备CCIE实验考试，这一部分还包括5套CCIE考试模拟题，以便给应试者一种身临其境的考试感觉。
本书主要对象是至少已经获得了CCNA或者CCDA证书的网络工程师。这些工程师们在阅读本书之前都已经对IP地址以及子网等知
