 For a majority of Service Providers, a significant portion of their revenues are still derived from data and voice services based on legacy transport technologies. Although Layer 3 MPLS VPNs fulfill the market need for some customers, they have some drawbacks. Ideally, carriers with existing legacy Layer 2 and Layer 3 networks would like to move toward a single backbone while new carriers would like to sell the lucrative Layer 2 services over their existing Layer 3 cores. The solution in these cases is a technology that would allow Layer 2 transport over a Layer 3 infrastructure. Layer 2 VPN Architectures introduces readers to Layer 2 Virtual Private Network (VPN) concepts, and describes Layer 2 VPN techniques via introductory case studies and comprehensive design scenarios. This book assists readers looking to meet those requirements by explaining the history and implementation details of the two technologies available from the Cisco Unified VPN suite: Any Transport over MPLS (ATOM) for MPLS-based cores and Layer 2 Tunneling Protocol version 3 (L2TPv3) for native IP cores. The structure of this book is focused on first introducing the reader to Layer 2 VPN benefits and implementation requirements and comparing them to those of Layer 3 based VPNs, such as MPLS, then progressively covering each currently available solution in greater detail.

 Definitive MPLS Network Designs provides examples of how to combine key technologies at the heart of IP/MPLS networks. Techniques are presented through a set of comprehensive design studies. Each design study is based on characteristics and objectives common to a given profile of network operators having deployed MPLS and discusses all the corresponding design aspects. The book starts with a technology refresher for each of the technologies involved in the design studies. Next, a series of design studies is presented, each based on a specific hypothetical network representative of service provider and enterprise networks running MPLS. Each design study chapter delivers four elements. They open with a description of the network environment, including the set of supported services, the network topology, the POP structure, the transmission facilities, the basic IP routing design, and possible constraints. Then the chapters present design objectives, such as optimizing bandwidth usage. Following these are details of all aspects of the network design, covering VPN, QoS, TE, network recovery, and—where applicable—multicast, IPv6, and pseudowire. The chapters conclude with a summary of the lessons that can be drawn from the design study so that all types of service providers and large enterprise MPLS architects can adapt aspects of the design solution to their unique network environment and objectives.  Prevent security breaches by deploying CSA, the Cisco host intrusion prevention system Learn the basics of endpoint security and why it is so important in today's security landscape Protect endpoint systems from hackers, viruses, and worms with host intrusion prevention security Prevent "Day-Zero" attacks with the first book on Cisco Security Agent (CSA) deployment Endpoint systems, being the point of execution for the malicious code, is where the most effective counter-intrustion mechanisms should be placed. Cisco Security Agent (CSA) is an important part of the network security puzzle that can help organizations secure their end systems. Its many capabilities include preventing "Day Zero" worm attacks, end system virus attacks, and Trojan horses; acting as a distributed firewall; performing an operating system lockdown; and performing application control. With the vast array of features, capabilities, and complexities associated with CSA, users need expert guidance to help them implement and maintain this important new security device and use it to maximum effect. This book presents a detailed explanation of CSA, illustrating the use of the product in a step-by-step fashion. The book presents a complete view of host intrusion prevention with CSA, including basic concepts, installations, tuning, and monitoring and maintenance. Part I discusses the need for end point security. Part II helps readers understand CSA building blocks. Part III delves into the primary concern of new customers, that being installation. Part IV covers monitoring and reporting issues. Part V covers CSA analysis features. Part VI discusses creating policies and CSA project implementation plans. Maintenance is covered in Part VII. Chad Sullivan is a triple-CCIE (Security, Routing/Switching, SNA/IP) and a systems engineer for Cisco Systems. Focusing predominantly on security in recent years, he is a member of the Security and VPN Virtual Teams at Cisco. |
