This is the eBook version of the printed book. If the print book includes a CD-ROM, this content is not included within the eBook version. Learn practical guidelines for designing and deploying a scalable BGP routing architecture Up-to-date coverage of BGP features like performance tuning, multiprotocol BGP, MPLS VPN, and multicast BGP In-depth coverage of advanced BGP topics to help design a complex BGP routing architecture Practical design tips that have been proven in the field Extensive configuration examples and case studies BGP Design and Implementation focuses on real-world problems and provides not only design solutions, but also the background on why they are appropriate and a practical overview of how they apply into a top-down design. The BGP protocol is being used in both service provider and enterprise networks. The design goals of these two groups are different, leading to different architectures being used in each environment. The title breaks out the separate goals, and resulting solutions for each group to assist the reader in further understanding different solution strategies. This book starts by identifying key features and functionality in BGP. It then delves into the topics of performance tuning, routing policy development, and architectural scalability. It progresses by examining the challenges for both the service provider and enterprise customers, and provides practical guidelines and a design framework for each. BGP Design and Implementation finishes up by closely looking at the more recent extensions to BGP through Multi-Protocol BGP for MPLS-VPN, IP Multicast, IPv6, and CLNS. Each chapter is generally organized into the following sections: Introduction, Design and Implementation Guidelines, Case Studies, and Summary.

A guide to designing and implementing VPLS services over an IP/MPLS switched service provider backbone Today's communication providers are looking for convenience, simplicity, and flexible bandwidth across wide area networks-but with the quality of service and control that is critical for business networking applications like video, voice and data. Carrier Ethernet VPN services based on VPLS makes this a reality. Virtual Private LAN Service (VPLS) is a pseudowire (PW) based, multipoint-to-multipoint layer 2 Ethernet VPN service provided by services providers By deploying a VPLS service to customers, the operator can focus on providing high throughput, highly available Ethernet bridging services and leave the layer 3 routing decision up to the customer. Virtual Private LAN Services (VPLS) is quickly becoming the number one choice for many enterprises and service providers to deploy data communication networks. Alcatel-Lucent VPLS solution enables service providers to offer enterprise customers the operational cost benefits of Ethernet with the predictable QoS characteristics of MPLS.

Design a robust BGP control plane within a secure, scalable network for smoother services A robust Border Gateway Protocol setup is vital to ensuring reliable connectivity, an essential capability for any organization. The Internet has become a necessary, always-on service in homes and businesses, and BGP is the protocol that keeps communication flowing. But BGP also has become crucial to delivery of intra-domain business services. But the network is only as reliable as BGP, so service enablement depends upon making BGP more stable, reliable, and service-rich. Alcatel-Lucent Service Router Operating System is engineered to bear the load of the most demanding networks. The system features support for Symmetric Multiprocessing and unprecedented depth of advanced routing features, all within a single OS that's supported across the entire Alcatel-Lucent IP/MPLS router portfolio. Versatile Routing and Services with BGP provides guidance toward implementation of BGP within SR-OS, and details the use and control of each feature. The book provides in-depth coverage of topics such as: BGP/MPLS IP-VPN, VPLS, VPWS Labeled Unicast IPv4, reconvergence, and multicast Security, graceful restart and error handling IPv6 PE (6PE) and IPv6 extensions to BGP/MPLS IP-VPN A look at forthcoming features such as Ethernet VPN Basic BGP competency is assumed, but the book is accessible even to those with zero familiarity with Alcatel-Lucent's SR-OS. It underscores the idea that BGP is more than just service enablement, and can also be used for infrastructure layer transport - but both layers must be solid, scalable, and able to quickly reconverge. Versatile Routing and Services with BGP demonstrates the creation of a robust BGP control plane within a, secure network, allowing the delivery of flawless, uninterrupted service.

A detailed examination of exterior routing protocols and advanced IP routing issues Routing TCP/IP, Volume II, enables you to: Master the operational components, configuration, and troubleshooting of BGP-4-the de facto interdomain routing protocol Understand the operation, configuration, and troubleshooting of NAT Learn how to deploy, configure, and troubleshoot IP multicast routing through an array of case studies and exercises Familiarize yourself with the design goals and current state of IPv6, the new generation of the IP protocol Implement router management through a diverse range of expert-tested methods Test and validate your knowledge with practical, comprehensive review questions, configuration exercises, and troubleshooting exercises Further your CCIE preparation while mastering advanced TCP/IP concepts The complexities of exterior gateway protocols, including TCP connections, message states, path attributes, interior routing protocol interoperation, and setting up neighbor connections, require a comprehensive understanding of router operations in order to manage network growth. Routing TCP/IP, Volume II, provides you with the expertise necessary to understand and implement Border Gateway Protocol Version 4 (BGP-4), multicast routing, Network Address Translation (NAT), IPv6, and effective router management techniques. Jeff Doyle's practical approach, easy-to-read format, and comprehensive topic coverage make this book an instant classic and a must-have addition to any network professional's library. Routing TCP/IP, Volume II, expands upon the central theme of Volume I: scalability and management of network growth. Volume II moves beyond the interior gateway protocols covered in Volume I to examine both inter-autonomous system routing and more exotic routing issues such as multicasting and IPv6. This second volume follows the same informational structure used effectively in Volume I: discussing the topic fundamentals, following up with a series of configuration examples designed to show the concept in a real-world environment, and relying on tested troubleshooting measures to resolve any problems that might arise. This book helps you accomplish more than earning the highly valued CCIE number after your name; it also helps you develop the knowledge and skills that are essential to perform your job at an expert level. Whether you are pursuing CCIE certification, need to review for your CCIE recertification exam, or are just looking for expert-level advice on advanced routing issues, Routing TCP/IP, Volume II, helps you understand foundation concepts and apply best practice techniques for effective network growth and management.
