Using TRILL, FabricPath, and VXLAN (eBook)

Virtualization has dramatically improved utilization within the datacenter: now, TRILL and FabricPath overlays can do the same for data center networks. Using them, you can distribute data traffic far more effectively, utilizing virtually all of your network links – thereby overcoming the greatest disadvantage of traditional Spanning Tree-based topologies. Now, for the first time, there's a practical, expert guide to creating high-efficiency MSDC overlay networks with TRILL and FabricPath.
Authored by two of Cisco's leading experts, Using TRILL and FabricPath:Offers comprehensive guidelines and references for planning MSDC environmentsReviews all key design considerations and offers practical implementation methodologiesDemonstrates TRILL and FabricPath at work through realistic deployment examplesShows how to migrate current Spanning Tree-based L2 networks to FabricPath and TRILLExplains how to ensure interoperability with other overlay technologies such as like VxLAN and NVGRE, and with your existing infrastructureProvides up-to-the-minute information on relevant advanced TRILL and FabricPath functionality for key Cisco platforms, including Nexus 7000, Nexus 5000, and Nexus 3000

Using TRILL, FabricPath, and VXLAN Designing Massively Scalable Data Centers with Overlays   TRILL, FabricPath, and VXLAN overlays help you distribute data traffic far more effectively, dramatically improving utilization in even the largest data center networks. Using TRILL, FabricPath, and VXLAN is the first practical and comprehensive guide to planning and establishing these high-efficiency overlay networks. The authors begin by reviewing today's fast-growing data center requirements, and making a strong case for overlays in the Massive Scale Data Center (MSDC). Next, they introduce each leading technology option, including FabricPath, TRILL, LISP, VXLAN, NVGRE, OTV, and Shortest Path Bridging (SPB). They also present a chapter-length introduction to IS-IS, focusing on details relevant to the control of FabricPath and TRILL networks. Building on this foundation, they offer in-depth coverage of FabricPath: its advantages, architecture, forwarding, configuration, verification, and benefits in Layer-2 networks. Through examples, they explain TRILL's architecture, functionality, and forwarding behavior, focusing especially on data flow. They also fully address VXLAN as a solution for realizing IP-based data center fabrics, including multi-tenant cloud applications.   Using TRILL, FabricPath, and VXLAN provides detailed strategies and methodologies for FabricPath, TRILL, and VXLAN deployment and migration, as well as best practices for management and troubleshooting. It also presents three detailed implementation scenarios, each reflecting realistic data center challenges. In particular, the authors show how to integrate multiple overlay technologies into a single end-to-end solution that offers exceptional flexibility, agility, and availability.   Sanjay K.
