Building MPLS-Based Broadband Access VPNs

Implement the design principles and configurations behind MPLS-based VPNs for broadband access networks

The book discusses how MPLS and its VPN service are best used in a broadband environment, concentrating on key design issues and solutions, including

• How to manage tens of thousands of interfaces and host routes and hundreds of dynamic VPNs
• When a Virtual Home Gateway is necessary
• Why use dynamic address assignment
• How routes should be summarized into the core

Deploy MPLS VPNs successfully in broadband networks with Building MPLS-Based Broadband Access VPNs. This book helps you understand why and how today's broadband networks function, covering the principal access technologies: DSL, Ethernet, and cable. The book also examines the different tunneling protocols used for VPN solutions today, namely GRE, IPSec, and L2TP, with examples of how these solutions are deployed and a discussion of their strengths and weaknesses.

Building MPLS-Based Broadband Access VPNs also includes an in-depth description of the IOS VRF Lite, which helps you use VRF-aware features with an IP core.

Detailed descriptions of the technologies, design principles, network configurations, and case studies are provided throughout the book, helping you develop a pragmatic understanding of MPLS-based broadband access VPNs.

• Obtain a realistic understanding of large-scale broadband access network design requirements
• Recognize the business impact of using MPLS to provide access VPN services, including the advantages of QoS, availability, and provisioning
• Use MPLS in access VPN and transport networks and deal with the unique scalability problems that such networks pose
• Leverage VRF-aware features to deploy IP-based VPNs
• Includes detailed Cisco IOS configuration examples based on real-world scenarios
