前言

随着数字经济的迅猛发展，网络技术作为数字经济的底座，其作用和价值正在受到前所未有的关注和重视。锐捷网络股份有限公司（以下简称“锐捷”）作为成立于2003年的老牌ICT民族品牌，是行业领先的网络基础设施及解决方案提供商，其始终致力于将技术与应用充分融合，创造性地解决客户问题。锐捷在全球拥有8大研发中心，8000余员工，业务范围覆盖80多个国家和地区，服务各行业客户数字化转型。锐捷认证体系不仅代表了网络技术、数据通信技术的行业至高标准，更是网络工程师们打开职业生涯晋升通道的黄金钥匙。本书的编者以及相关参编单位，亲历、研究锐捷认证体系（从早先的RCNA到之后的RCNP再到如今的RCIE）都超过十年之久，更有以国育产教融合教育科技（海南）有限公司为代表的一直在培养和使用锐捷认证工程师的适配锐捷体系的人才供应商和技术服务商，他们对锐捷认证体系的了解以及锐捷体系认证工程师的价值的认知，极为深刻、极为具象、极为有发言权。锐捷认证互联网专家（RCIE）作为锐捷认证体系中的最高级别认证，其认证过程严格而富有挑战性。RCIE认证需要考生具备深厚的理论基础和丰富的实战经验。该认证近几年才推出，一经推出，就成为了广大网络工程师提升自己、追求卓越的通关之选。不过，市面上关于RCIE认证考试的指南和教材几乎是空白的，这也给广大工程师的备考之路增加了障碍。在此背景下，本书编者及参编单位为了满足广大网络工程师对RCIE认证的学习需求，特地编写了《锐捷认证互联网专家RCIE&RS理论指南（上册）》、《锐捷认证互联网专家RCIE&RS理论指南（下册）》和《锐捷认证互联网专家RCIE&RS实验指南》。理论指南编写以理论为主和案例分析为辅，实验指南帮助读者深入理解锐捷网络技术的原理和应用，掌握锐捷网络设备的配置和管理技能，为其顺利通过RCIE认证打下坚实的基础。图书具有以下特色：
1.金牌团队，赋能RCIE人才培养
图书作者由锐捷金牌讲师、国家教学名师、锐捷RCIE认证讲师等资深锐捷人共同编写，教材全面融入RCIE认证最新标准，理实结合，学以致用。
2.书证融通实战派，让您行驶在RCIE认证快车道
RCIE&RS理论指南（上册）共包含16章，通过案例分析形式详实讲解了IS-IS、BGP、组播路由协议等原理。RCIE&RS理论指南（下册）共包含18章，通过案例分析形式详实讲解了MPLS、PMLS VPN、IPSec VPN、IPv6、SR路由、QoS等原理。RCIE&RS实验指南共包含39个实战案例，通过锐捷官方模拟器，详实讲解了锐捷网络技术的应用，让读者在实践中更深入理解RCIE&RS的技术应用。
3.配套资源丰富，与RCIE认证同步更新
图书配套锐捷官方模拟器、实验拓扑、配置手册、模拟题库等电子资源，并动态同步RCIE认证。
