MPLS is driving next-generation IP networks by offering reliable, cost-effective revenue generation through implementation of converged services. It is also gaining momentum in service provider and enterprise markets due to its capability to provide speed, classes of service, and high availability. Key to effective service deployment, however, is knowing how to configure MPLS. MPLS Configuration on Cisco IOS Software fills the market need for books that go beyond theory and show users how to work with Cisco IOS Software to implement MPLS. The book shows readers the configurations involved in deploying MPLS networks on a small scale through a series of self-study lab-based scenarios, providing a solid foundation of the technology and the nuances involved with its configuration. The authors provide a baseline template for MPLS configuration and its features in different real-world deployment scenarios. The book does not delve into the detailed, theoretical aspects of MPLS; rather, it provides readers with practical guidance on the configuration of MPLS on Cisco routers. Readers will learn configuration guidelines for MPLS implementations available in Cisco IOS. They'll learn to implement Virtual Private LAN Services (VPLS) and also Layer 2 VPNs with Cisco's AToM.
