Résumé

The complete network engineer's guide to MPLS-based VPNs

Maximizing VPN security, scalability, stability, and manageability
Design, deployment, and management—start to finish
Powerful BGP design techniques that avoid key problems
Deployment models for ADSL, cable, mobile/wireless, and dial access VPNs

Multiprotocol Label Switching (MPLS) enables enterprises and service providers to supercharge their virtual private networks (VPNs), dramatically improving scalability, performance, security, and efficiency. In MPLS-Based VPNs: Designing Advanced Virtual Networks, two leading Cisco experts give network engineers comprehensive guidance on implementing MPLS in any VPN environment. Drawing on their extensive practical experience with MPLS, Peter Tomsu and Gerhard Weiser present start-to-finish coverage of design, deployment, and management. Coverage includes:

Understanding the functionality of IP-based MPLS VPNs
Comparing MPLS to alternative solutions: key benefits and essential tradeoffs
Route distribution, VPN topologies, encapsulation, label distribution, and other key techniques and features
Advanced Border Gateway Protocol (BGP) design techniques that avoid the most common VPN problems
Enterprise deployment models for Asymmetric Digital Subscriber Line (ADSL), cable, mobile/wireless, and dial access VPNs
MPLS for Layer 2 and Layer 3 VPN architectures
Current and future MPLS VPN applications

If you're ready to optimize the performance and value of your enterprise VPN, this systematic guide will show you how-every step of the way.
