A comprehensive introduction to all facets of MPLS theory and practice

Helps networking professionals choose the suitable MPLS application and design for their network

Provides MPLS theory and relates to basic IOS configuration examples

The Fundamentals Series from Cisco Press launches the basis to readers for understanding the purpose, application, and management of technologies

MPLS has emerged as the new networking layer for service providers throughout the world. For many service providers and enterprises MPLS is a way of delivering new applications on their IP networks, while consolidating data and voice networks. MPLS has grown to be the new default network layer for service providers and is finding its way into enterprise networks as well. This book focuses on the building blocks of MPLS (architecture, forwarding packets, LDP, MPLS and QoS, CEF, etc.). This book also reviews the different MPLS applications (MPLS VPN, MPLS Traffic Engineering, Carrying IPv6 over MPLS, AToM, VPLS, MPLS OAM

etc.).

You will get a comprehensive overview of all the aspects of MPLS, including the building blocks, its applications, troubleshooting and a perspective on the future of MPLS.

Good book. Misleading name., November 21, 2007

By Gaurav Taparia "just a reader" (CO USA) - See all my reviews

This review is from: MPLS Fundamentals (Paperback)

This is a fairly exhaustive book on cisco MPLS implementation. The name "MPLS Fundamentals" gives an idea that this is a good place to start with, ut unfortunately not. It starts at a basic level, but in no time dives in deep. Use this book only if you want to understand specific areas in depth and not for an overview. Also, if you have access to your own lab, you will find it much easier to follow along. Help other customers find the most helpful reviews

Boring to read but easy to udnerstand, May 2, 2010

By Kambiz Agahian "Sr. Network Architect (CCIE R&S)" (USA (CA)) - See all my reviews

Amazon Verified Purchase(What's this?)

This review is from: MPLS Fundamentals (Paperback)

As a CCIE instructor I recommend this book in many of my classes but still the main problem with the book is that the author uses a veeeery boring and lengthy language to explain even easy and straightforward topics. I'd approve this kind of text for a CCNA book but when it comes to a CCIE level MPLS discussion it just takes more and more time and makes the reader bored until it actually gets a simple message through. This however might have been a great idea to make sure the reader remains thirsty on every single page, sadly the way this book is developed prevents this from happening so you read and read and always that very word/sentence seems to remain far away until the student loses the lead. This particular issue does occur multiple times in different chapters. I don't blame the authors but certainly the technical reviewers and editors could have pruned things off a little bit to make sure readers get the most out of their time. But from a technical stand point this book covers... Read more Help other customers find the most helpful reviews

Excellent level of detail and insight, March 23, 2008

By Tawfiq K. Khan - See all my reviews

This review is from: MPLS Fundamentals (Paperback)

This is a book where you are given not only an in depth what it is and how its implemented of the protocol but you are also given great insight as to the why its done this way. You are given all of this in a very readable format. I agree with another reviewer that this is an exhaustive text into the internals of MPLS. I love the level of detail it goes into.
