Description

The CCIE Routing and Switching certification is the most respected certification in the industry. The successful CCIE candidate must understand a broad range of network technologies that includes OSI model, bridging, LAN switching, IP and IP Routing protocols, multicast, WAN technologies, and performance management. The exam is notoriously difficult and CCIE candidates must first pass a qualifying written exam. The CCIE Routing and Switching Exam Certification Guide, Second Edition covers all of the topics of the written exam. In this updated edition there are content and alignment changes based on the revised exam and networking trends. For example, there is deeper and greater coverage of MPLS, security, and BGP and BGP designs. New chapters covering IPv6 and IS-IS will be included. Also new to this edition are more challenging exam questions to match the difficulty of the actual exam and the CD-ROM is enhanced with a 500-question exam engine from Boson Software. This book also contains all the elements and features of the best-selling Exam Certification Guide series. These elements include specially designed assessment and study features, such as "Do I Know This Already?" quizzes that assess readers' knowledge and help them decide how much time to spend on each section, Foundation Summary sections that highlight essential concepts for quick reference, and End-of-chapter questions to quiz readers.show more
