TCP/IP路由技術(shù)(第二卷)(英文版)

內(nèi)容概要

本書深入系統(tǒng)地闡述了TCP/IP路由技術(shù)，內(nèi)容包括幾種重要的網(wǎng)絡(luò)協(xié)議，如外部網(wǎng)關(guān)協(xié)議(EGP)、邊界網(wǎng)關(guān)協(xié)議(BGP4)，以及相應(yīng)的高級IP路由技術(shù)與應(yīng)用——網(wǎng)絡(luò)地址轉(zhuǎn)換、IP組播路由技術(shù)、IPv6技術(shù)、路由器管理等。本書共分9個章節(jié)，首先介紹并討論了主題內(nèi)容的基本原理，接著是設(shè)計(jì)用來展示真實(shí)網(wǎng)絡(luò)環(huán)境中相關(guān)概念的一系列配置范例，最后提供給讀者經(jīng)實(shí)踐驗(yàn)證過的故障排除方法以解決網(wǎng)絡(luò)可能會出現(xiàn)的問題。重點(diǎn)介紹了自治系統(tǒng)之間的路由選擇策略以及諸如組播和IPv6等更具挑戰(zhàn)性的路由選擇和實(shí)施技術(shù)。
    　　本書內(nèi)容全面，可讀性強(qiáng)，含有協(xié)議配置、網(wǎng)絡(luò)實(shí)施、故障排除等方面的大量實(shí)例，是備戰(zhàn)CCIE認(rèn)證考試的經(jīng)典之作，適合CCIE開發(fā)人員、網(wǎng)絡(luò)與通信系統(tǒng)工程技術(shù)人員閱讀。
