TCP/IP 路由技術(英文版)（簡體書）

本書深入系統地闡述了TCP/IP路由技術，內容包括幾種重要的網絡協議，如外部網關協議（EGP）、邊界網關協議（BGP4），以及相應的高級IP路由技術與應用——網絡地址轉換、IP組播路由技術、IPv6技術、路由器管理等。本書共分9章，首先介紹并討論了有關主題的基本原理，接著是設計用來展示實際網絡環境中相關概念的一系列配置范例，最后提供給讀者經實踐驗證過的故障排除方法以解決網絡可能會出現的問題。重點介紹了自治系統之間的路由選擇策略以及諸如組播和IPv6等更具挑戰性的路由選擇和實施技術。
本書內容全面，可讀性強，含有協議配置、網絡實施、故障排除等方面的大量實例，是備戰CCIE認證考試的經典之作，適合準備參加CCIE考試的人員、網絡與通信系統工程技術人員閱讀。
