Prepare for CCNP or CCDP certification with the official BSCN Coursebook

• Understand the principles of classful and classless routing and the difference between link-state and distance vector protocol behavior
• Select and configure the appropriate services for simplifying IP address management at branch offices by proper address allocation and summarization
• Implement the appropriate technologies for a scalable, routed network that uses link-state protocols and redistribution
• Configure edge routers to properly interconnect to a BGP network through either a single or multihomed interconnection
• Control and optimize routing update information by implementing filters, metrics, and policy-based routing and changing administrative distance
• Examine case studies that show you how to build a scalable internetwork including multiple routing protocols

Based on the new BSCN instructor-led course developed by Cisco Systems, Building Scalable Cisco Networks teaches you how to design, configure, maintain, and scale routed networks that are growing in size and complexity. This book focuses on using Cisco routers connected in LANs and WANs typically found at medium to large network sites. Upon completion of this book, you will be able to select and implement the appropriate Cisco IOS. Software services required to build scalable, routed networks.

As the replacement for the Advanced Cisco Router Configuration (ACRC) course, BSCN is one of four new courses recommended by Cisco for Cisco Certified Network Professional (CCNP) and Cisco Certified Design Professional (CCDP) preparation.

In Building Scalable Cisco Networks you will study a broad range of technical details on topics related to routing, including routing principles, IP addressing issues such as variable-length subnet masks (VLSMs), route summarization, and protocol redistribution. The routing protocols Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), and Border Gateway Protocol (BGP) are investigated in detail. Configuration examples and sample verification output demonstrate troubleshooting techniques, and a case study is used throughout the book to review key concepts and to discuss critical issues surrounding network operation. Chapter-ending configuration exercises and review questions illustrate and help solidify the concepts presented in the book.
