&>Building Cisco Multilayer Switched Networks (BCMSN) Fourth Edition Foundation learning for CCNP 642-812 BCMSN Richard Froom, CCIE(R) No. 5102Balaji SivasubramanianErum Frahim, CCIE No. 7549 Authorized Self-Study Guide: Building Cisco Multilayer Switched Networks (BCMSN), Fourth Edition, is a Cisco(R) authorized, self-paced learning tool for CCNP(R) switching foundation learning. You will learn how to create scalable multilayer switched networks by installing, configuring, monitoring, and troubleshooting network infrastructure equipment for a campus switched network and integrate advanced technologies such as VoIP and wireless. This comprehensive book provides detailed information and easy-to-grasp tutorials on advanced skills in design, configuration, operation, and troubleshooting of enterprise level switched networks, including converged IP data, voice, and Airespace wireless LAN (WLAN) connectivity. The book assumes only a basic understanding of networking so it provides a great deal of detail on the topics covered. This book is ideal for certification candidates who are seeking a self-paced tool to learn the material covered in the latest BCMSN exam. Each chapter opens with the list of topics covered to clearly identify the focus of that chapter. At the end of each chapter, Study Tips list the main points related to the BCMSN exam. A summary of key concepts for quick study and review questions provide you with an opportunity to assess and reinforce your understanding of the material. Real-world case studies help illuminate theoretical concepts. In addition, chapters that cover Catalyst configurations also include configuration exercises. Most of these are small-scale exercises that can be performed on a single switch. The goal of using small-scale exercises is to enable network professionals to practice the configuration exercises with only a single switch. Richard Froom, CCIE(R) No. 5102, is a technical leader for the Data Center, Switching and Wireless (DSW), and Storage Area Networking (SAN) Test Lab at Cisco. Balaji Sivasubramanian, CCNP, is an escalation engineer for the Gigabit Switching Business Unit (GSBU) at Cisco. Erum Frahim, CCIE No. 7549, is a senior support engineer working for the Data Center, DSW, and SAN Test Lab at Cisco. Provides a thorough introduction to campus switched network construction, support, and security Explains the fundamentals of multilayer switched network design and specific design features such as Spanning Tree Protocol, quality of service (QoS), and high availability Covers virtual LAN (VLAN) and InterVLAN Routing implementation Incorporates wireless client access and configuring campus switches to support voice technologies Uses extensive configuration examples and diagrams to solidify the explanations of topics Presents self-assessment review questions, configuration exercises, chapter objectives and summaries, and study tips to ensure information recall
