This session covers in detail the concepts of the Dynamic Multipoint VPN (DMVPN) solution. It starts with an overview of basic DMVPN functionality including in-depth descriptions of how Next Hop Resolution Protocol (NHRP) is used in DMVPN hub-and-spoke and dynamic spoke-spoke networks, including DMVPN Phase 2 and Phase 3 functionality and discussion and examples of using DMVPN for Network Virtualization with VRF-lite and 2547oDMVPN. The session also covers how DMVPN interacts with NAT, QoS, MPLS, and dynamic routing. This session is for designers, managers, and troubleshooters of extended corporate DMVPNs and for service providers that are deploying these services for their customers.

Walter Goralski "The Illustrated Network: How TCP/IP Works in a Modern Network"
Morgan Kaufmann | 2008-12-19 | ISBN: 0123745411 | 832 pages | PDF | 9,3 MB

In 1994, W. Richard Stevens and Addison-Wesley published a networking classic: TCP/IP Illustrated. The model for that book was a brilliant, unfettered approach to networking concepts that has proven itself over time to be popular with readers of beginning to intermediate networking knowledge. The Illustrated Network takes this time-honored approach and modernizes it by creating not only a much larger and more complicated network, but also by incorporating all the networking advancements that have taken place since the mid-1990s, which are many.

This book takes the popular Stevens approach and modernizes it, employing 2008 equipment, operating systems, and router vendors. It presents an ?illustrated? explanation of how TCP/IP works with consistent examples from a real, working network configuration that includes servers, routers, and workstations. Diagnostic traces allow the reader to follow the discussion with unprecedented clarity and precision. True to the title of the book, there are 330+ diagrams and screen shots, as well as topology diagrams and a unique repeating chapter opening diagram. Illustrations are also used as end-of-chapter questions. A complete and modern network was assembled to write this book, with all the material coming from real objects connected and running on the network, not assumptions. Presents a real world networking scenario the way the reader sees them in a device-agnostic world. Doesn?t preach one platform or the other.

TCP/IP Tutorial and Technical Overview is an exceptionally complete, easy-to-understand, and up-to-date guide to the protocols that drive the Internet. Ideal for beginners—and for networking professionals who want to deepen their understanding—this book covers the entire TCP/IP suite, including emerging protocols that address the Internet's key challenges.

The authors—an expert team of IBM TCP/IP instructors and consultants—begin by introducing TCP/IP's fundamental goals, roles, components, and underlying concepts. They survey today's core TCP/IP application protocols, from DNS to HTTP, SMTP to RTP, as well as protocols designed for advanced wireless and multimedia applications.

The book includes detailed coverage of the latest trends in networking and infrastructure, including Quality of Service, MPLS, security, IP mobility, IP telephony, and IPv6. The authors also introduce leading tools for maximizing availability and scalability in IBM and Cisco environments, including IBM Sysplex Distributor, Cisco MultiNode Load Balancing, and OS/390 DNS/WLM.
