As data centers grow in size and complexity, enterprises are adopting server virtualization technologies such as VMware, VMotion, NIC teaming, and server clustering to achieve increased efficiency of resources and to ensure business resilience. However, these technologies often involve significant expense and challenges to deal with complex multisite interconnections and to maintain the high availability of network resources and applications. Interconnecting Data Centers Using VPLS presents Virtual Private LAN Service (VPLS) based solutions that provide high-speed, low-latency network and Spanning Tree Protocol (STP) isolation between data centers resulting in significant cost savings and a highly resilient virtualized network. The design guidance, configuration examples, and best practices presented in this book have been validated under the Cisco Validated Design (CVD) System Assurance program to facilitate faster, more reliable and more predictable deployments. The presented solutions include detailed information about issues that relate to large Layer 2 bridging domains and offer guidance for extending VLANs over Layer 3 networks using VPLS technology. Implementing this breakthrough Data Center Interconnect (DCI) strategy will evolve your network to support current server virtualization techniques and to provide a solid foundation for emerging approaches. The book takes you from the legacy deployment models for DCI, problems associated with extending Layer 2 networks, through VPN technologies, to various MST-, EEM-, and GRE-based deployment models and beyond. Although this book is intended to be read cover-to-cover, it is designed to be flexible and allow you to easily move between chapters to develop the solution most compatible with your requirements. Describes a variety of deployment models to effectively transport Layer 2 information, allowing your virtualization solution to operate effectively Explains benefits and trade-offs of various solutions for you to choose the solution most compatible with your network requirements to ensure business resilience Provides detailed design guidance and configuration examples that follow Cisco best practice recommendations tested within the CVD This book is part of the Networking Technology Series from Cisco Press®, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

This book describes Cisco's break-through solutions that solve the network traffic problems created by Virtualization technologies.- Design guidance and configuration examples that follow Cisco best practice recommendations for the new Data Center Interconnect strategy.- Multiple deployment models provided for readers to choose the solution most compatible with their requirements to ensure their business resiliency.- Thorough description of data center technologies used in the deployment solutions. Data availability and business resiliency is becoming a critical requirement for a wide range of enterprises. To address these issues, organizations provide dedicated networks to guarantee performance and high availability. However, this approach can involve significant expenses and complexity. Organizations require cost-effective, comprehensive solutions that provide for economical, efficient, and effective deployment of a network that allows business resiliency. Companies today typically deploy two separate networks: one network for Layer 3, and an optical network that is dedicated to virtualization technologies. Today, these virtualization technologies require Layer 2 connectivity, which has caused an expansion of Layer 2 domains. Larger networks must provide the required Layer 2 connectivity to ensure high availability between geographically dispersed data centers. As a result, customers are facing issues such as maintaining the high availability of applications and dealing with complex multi-site interconnections. Companies require a deployment that effectively transports Layer 2 information, which allows a virtualization solution to operate effectively. The solutions in this book offer significant cost savings by eliminating the need for a dedicated optical network.
