內(nèi)容簡介

　　查看本書中文版本書是第一本詳細而又完整地介紹互聯(lián)網(wǎng)內(nèi)部網(wǎng)關(guān)路由選擇協(xié)議（IGP協(xié)議）的專業(yè)書籍，堪稱有關(guān)IGP協(xié)議方面不可多得的經(jīng)典之作。本書共分三個部分。第一部分主要介紹了網(wǎng)絡(luò)和路由選擇的基本知識，對TCP/IP協(xié)議和靜態(tài)、動態(tài)路由選擇技術(shù)作了一個整體的回顧。第二部分是本書的精華，這一部分詳細深入地講述了各種常用的內(nèi)部網(wǎng)關(guān)路由選擇協(xié)議，如靜態(tài)路由、RIP、RIPv2、IGRP、EIGRP、OSPF、ISIS等，每一章除了對該協(xié)議的實現(xiàn)機制和參數(shù)詳盡闡述，使讀者對協(xié)議的實現(xiàn)原理有一個清晰的理解外，還通過在實際網(wǎng)絡(luò)環(huán)境中的實例，詳細地論述了該協(xié)議在Cisco路由器上的配置和故障處理方法，使讀者獲取大量解決實際問題的專業(yè)技能。第三部分介紹了如缺省路由、路由過濾等多種有效的路由控制工具，用來創(chuàng)建和管理多個IP路由選擇協(xié)議的協(xié)調(diào)工作。本書的讀者不僅是那些需要準備通過CCIE考試的考生，也是任何需要完整理解TCP/IP內(nèi)部路由選擇協(xié)議的網(wǎng)絡(luò)設(shè)計和工程人員。本書中對協(xié)議細節(jié)的講解和對網(wǎng)絡(luò)實例的探討相信會讓讀者獲益非淺。
