前言
隨著數字經濟的迅猛發展，網絡技術作為數字經濟的底座，其作用和價值正在受到前所未有的關注和重視。銳捷網絡股份有限公司（以下簡稱“銳捷”）作為成立于2003年的老牌ICT民族品牌，是行業領先的網絡基礎設施及解決方案提供商，其始終致力于將技術與應用充分融合，創造性地解決客戶問題。銳捷在全球擁有8大研發中心，8000余員工，業務范圍覆蓋80多個國家和地區，服務各行業客戶數字化轉型。銳捷認證體系不僅代表了網絡技術、數據通信技術的行業至高標準，更是網絡工程師們打開職業生涯晉升通道的黃金鑰匙。本書的編者以及相關參編單位，親歷、研究銳捷認證體系（從早先的RCNA到之后的RCNP再到如今的RCIE）都超過十年之久，更有以國育產教融合教育科技（海南）有限公司為代表的一直在培養和使用銳捷認證工程師的適配銳捷體系的人才供應商和技術服務商，他們對銳捷認證體系的了解以及銳捷體系認證工程師的價值的認知，極為深刻、極為具象、極為有發言權。銳捷認證互聯網專家（RCIE）作為銳捷認證體系中的最高級別認證，其認證過程嚴格而富有挑戰性。RCIE認證需要考生具備深厚的理論基礎和豐富的實戰經驗。該認證近幾年才推出，一經推出，就成為了廣大網絡工程師提升自己、追求卓越的通關之選。不過，市面上關于RCIE認證考試的指南和教材幾乎是空白的，這也給廣大工程師的備考之路增加了障礙。在此背景下，本書編者及參編單位為了滿足廣大網絡工程師對RCIE認證的學習需求，特地編寫了《銳捷認證互聯網專家RCIE&RS理論指南（上冊）》、《銳捷認證互聯網專家RCIE&RS理論指南（下冊）》和《銳捷認證互聯網專家RCIE&RS實驗指南》。理論指南編寫以理論為主和案例分析為輔，實驗指南幫助讀者深入理解銳捷網絡技術的原理和應用，掌握銳捷網絡設備的配置和管理技能，為其順利通過RCIE認證打下堅實的基礎。圖書具有以下特色：
1.金牌團隊，賦能RCIE人才培養
圖書作者由銳捷金牌講師、國家教學名師、銳捷RCIE認證講師等資深銳捷人共同編寫，教材全面融入RCIE認證最新標準，理實結合，學以致用。
2.書證融通實戰派，讓您行駛在RCIE認證快車道
RCIE&RS理論指南（上冊）共包含16章，通過案例分析形式詳實講解了IS-IS、BGP、組播路由協議等原理。RCIE&RS理論指南（下冊）共包含18章，通過案例分析形式詳實講解了MPLS、PMLS VPN、IPSec VPN、IPv6、SR路由、QoS等原理。RCIE&RS實驗指南共包含39個實戰案例，通過銳捷官方模擬器，詳實講解了銳捷網絡技術的應用，讓讀者在實踐中更深入理解RCIE&RS的技術應用。
3.配套資源豐富，與RCIE認證同步更新
圖書配套銳捷官方模擬器、實驗拓撲、配置手冊、模擬題庫等電子資源，并動態同步RCIE認證。
