A guide for those using and defining MPLS VPN services Empowers network designers and engineers to investigate the options and benefits of IP/MPLS virtual private network (VPN) migration Covers the business rationale for implementing IP/MPLS VPNs Includes detailed configuration examples showing the steps necessary for full IP/MPLS VPN operation Presents detailed case studies illustrating key migration issues Major service providers worldwide are ramping up VPNs over IP and, since 2002, migrating from Layer 2 connections to Layer 3 IP MPLS/VPNs, indicating that IP MPLS/VPNs are the primary growth vehicle for service provider to enterprise connections. IP MPLS/VPNs are attractive for both parties. For enterprises, they enable right-sourcing of WAN services and yield generous operational cost savings. For service providers, they offer a higher level of service to customers and lower costs for service deployment. With migration comes challenge, however. Enterprises must understand key migration issues, what the realistic benefits are, and how to optimize new services. Providers must know what aspects of their services give value to enterprises and how they can provide the best value to customers. MPLS VPN Services for Converged Enterprise Networks provides enterprise network engineers the ability to analyze migration options, anticipate migration issues, and properly deploy IP/MPLS VPNs. Detailed configurations illustrate effective deployment, while case studies present available migration options and walk engineers through selecting the best option for the example network. Part I addresses the business case for moving to an IP/MPLS VPN network, with a chapter devoted to the business and technical issues that should be reviewed when evaluating IP MPLS/VPN offerings from major providers. Part II includes detailed deployment guidelines for the technologies used in the IP/MPLS VPN.
