MPLS and VPN Architectures (Networking Technology)


Product Description
A practical guide to understanding, designing, and deploying MPLS and MPLS-enabled VPNs
- In-depth analysis of the Multiprotocol Label Switching (MPLS) architecture
- Detailed discussion of the mechanisms and features that constitute the architecture
- Learn how MPLS scales to support tens of thousands of VPNs
- Extensive case studies guide you through the design and deployment of real-world MPLS/VPN networks
- Configuration examples and guidelines assist in configuring MPLS on Cisco devices
- Design and implementation options help you build various VPN topologies
Multiprotocol Label Switching (MPLS) is an innovative technique for high-performance packet forwarding. There are many uses for this new technology, both within a service-provider environment and within the enterprise network, and the most widely deployed usage today is the enabling of Virtual Private Networks (VPNs). With the introduction of MPLS-enabled VPNs, network designers are able to better scale their networks than with the methods available in the past.
Network engineers and administrators need quick, effective education on this technology to efficiently deploy MPLS-enabled VPNs within their networks. With that goal in mind, MPLS and VPN Architectures provides an in-depth discussion particular to Cisco's MPLS architecture. This book covers MPLS theory and configuration, network design issues, and case studies as well as one major MPLS application: MPLS-based VPNs. The MPLS/VPN architecture and all its mechanisms are explained with configuration examples, suggested design and deployment guidelines, and extensive case studies.
MPLS and VPN Architectures is your practical guide to understanding, designing, and deploying MPLS and MPLS-based VPNs.
</p>MPLS and VPN Architectures (Networking Technology) Review
I read this book in preparation for my Cisco MPLS exam, on my way to becoming a CCIP. I bought the 2 volumes. After reading the first one, I decided not to go ahead with the second. I work for a giant service provider, which is a fortune 500 company as well. I specifically work at the core network level. The core network transitioning from legacy SDH towards a pure IP/MPLS solution meant for me a fundamental understanding of MPLS.First of all, never throughout the book did I understand what exactly was the problem that MPLS was aimed at solving. The words are there and you will read them 3 or 4 times. But nothing will sink in.
Configuration examples are there alright, but there was no clear, separate explanation of each and every component of the architecture. When and where do we use MP-BGP, where do we redistribute which protocol, and so forth. You will have to do a lot of figuring out on your own, which will certainly mean a lot of guessing. And that is NOT why I bought a book on MPLS and VPNs :-)
This is not a book written in a style which assumes that you know nothing about the subject. On the contrary, it is so complicated that I think you need to know everything beforehand, and this book is only for reference ! This is certainly NOT a book for MPLS dummies (like myself).
The above conclusions I arrived at after I read one specific resource. Try to read the Cisco authorized course material, which is simply the instructor projector slides printed on paper, and a little explanation under it. Forget about the exam for a little while. For whoever is interested in REALLY understanding MPLS, and really understanding where each protocol goes, and the where and how and why of almost anything related to MPLS and VPNs, read that resource. Then compare it to this book. You will get my point.
