Design, operate, and troubleshoot advanced Cisco IP multicast in enterprise, data center, and service provider networks

IP Multicast, Volume II thoroughly covers advanced IP multicast designs and protocols specific to Cisco routers and switches. It offers a pragmatic discussion of common features, deployment models, and field practices for advanced Cisco IP multicast networks, culminating with commands and methodologies for implementation and advanced troubleshooting.

After fully discussing inter-domain routing and Internet multicast, the authors thoroughly explain multicast scalability, transport diversification, and multicast MPLS VPNs. They share in-depth insights into multicast for the data center, a full chapter of best-practice design solutions, and a start-to-finish troubleshooting methodology designed for complex environments.

Reflecting the authors’ extensive experience with service provider and enterprise networks, IP Multicast, Volume II will be indispensable to IP multicast engineers, architects, operations technicians, consultants, security professionals, and collaboration specialists. Network managers and administrators will find its case studies and feature explanations especially valuable.

• Understand the fundamental requirements for inter-domain multicast
• Design control planes for identifying source and receiver, as well as the downstream control plane
• Support multicast transport where cloud service providers don’t support native multicast
• Use multicast VPNs to logically separate traffic on the same physical infrastructure
• Explore the unique nuances of multicast in the data center
• Implement Virtual Port Channel (vPC), Virtual Extensible LAN (VXLAN), and Cisco’s Application Centric Infrastructure (ACI)
• Design multicast solutions for specific industries or applications
• Walk through examples of best-practice multicast deployments
• Master an advanced methodology for troubleshooting large IP multicast networks

Josh Loveless, CCIE No. 16638, is a systems engineering manager for Cisco Systems. He has been with Cisco since 2012, providing architecture and support services for tier 1 service providers as well as for many of Cisco’s largest enterprise customers, specializing in large-scale routing and switching designs. Prior to joining Cisco, he spent 15 years working for large service providers and enterprises as both an engineer and an architect, as well as providing training and architecture services to some of Cisco’s trusted partners. Josh maintains two CCIE certifications, Routing and Switching and Service Provider.

Ray Blair, CCIE No. 7050, is a distinguished systems engineer and has been with Cisco Systems since 1999. He uses his years of experience to align technology solutions with business needs to ensure customer success. Ray started his career in 1988, designing industrial monitoring and communication systems. Since that time, he has been involved with server/database administration and the design, implementation, and management of networks that included networking technologies from ATM to ZMODEM. He maintains three CCIE certifications in Routing and Switching, Security, and Service Provider (No. 7050), and he is also a Certified Information Systems Security Professional (CISSP), and a Certified Business Architect (No. 00298). Ray is coauthor of three Cisco Press books, Cisco Secure Firewall Services Module, Tcl Scripting for Cisco IOS, and IP Multicast, Volume 1. He speaks at many industry events and is a Cisco Live distinguished speaker.

Some of his focuses have been on security, multicast, network virtualization, data center enterprise cloud adoption, automation, and software-defined infrastructure, and he has authored several white papers on various technologies. He has been involved in multicast designs for several enterprise customers in different verticals. He is also one of the contributors to the framework for the Advanced Services Multicast Audit tool, which helps customers assess their operational multicast network to industry best practices. Arvind maintains two CCIE certifications, Routing and Switching and Security, and also is a Certified Business Architect. He holds a bachelor of science degree in electronics and communication, a master’s degree in electrical engineering, and a master’s degree in business administration. He has coauthored four Cisco Press books: Cisco Secure Firewall Services Module, Virtual Routing in the Cloud, Tcl Scripting for Cisco IOS, and IP Multicast:, Volume 1. He has also coauthored IEEE WAN smart grid architecture and presented in many industry forums, such as IEEE and Cisco Live.

IP multicast is central to today’s enterprise and service provider networks. However, the set of technologies and practices surrounding IP multicast has evolved and matured: older books on the topic are severely out of date. IP Multicast Architectures offers comprehensive guidance for deploying modern IP multicast systems of all kinds: basic and advanced, enterprise and service provider.

Focused on Cisco devices and technologies, IP Multicast Architectures addresses common features, deployment models, and field best practices. Each section offers immersive real-world explanations of multicast theory, and present multiple case studies showcasing best-practice multicast design methodologies. Each case study is carefully crafted to offer pragmatic “first-hand” guidance for building the right network for each environment and set of applications.

Coverage includes Layer 2 and Layer 3 multicast; routing, forwarding, domains, inter-domain routing, wireless multicast forwarding, Inter-AS, mVPN, mVRF, cloud mVPN transport, and much more. Throughout, the authors’ configurations, designs, features, and parameters reflect all that’s been learned since IP multicast first became widespread.

• Practical coverage of IP multicast networking in data center, service provider, campus, wireless, and enterprise environments
• Easy-to-follow configuration guides for specific multicast implementations, from basic to advanced
• A definitive guide to advanced IP multicast theory
• Expert advice on selecting the right multicast technology or deployment for each scenario
• Detailed explanations of cross Internet and large overlay multicast operations
