If you are in the market for a good MPLS resource, check out the Cisco Press book MPLS Fundamentals: A Comprehensive Introduction to MPLS Theory and Practice. I've nearly finished reading this over the past few weeks and it's definitely a great place to start if you have never really worked with MPLS.
Of course, everyone is still waiting for an MPLS CBT Nugget from Jeremy. However, until something like that is created - if you need to know more about the technology this is a great resource.
Each chapter includes a standard introduction and learning objectives. The various topics and sections are well laid out. The ATM chapter seems a bit dated, but there are still legacy networks lingering out there that may require some knowledge on the topic. Each chapter ends with a set of review questions to test your knowledge.
While reading this book, I would recommend you have a lab to practice the commands. Even if it's a simple three router triangle, you can configure the "mpls ip" interface command, run show commands to see labels get assigned, and run debug and show commands to verify LDP is operating correctly.
For reference, the table of contents for this book are as follows:
- Part 1 - Fundamentals of MPLS
- Chapter 1 - The Evolution of MPLS
