I must admit that I was quite perplexed by this book. MPLS is not my strongest area of study - this book did not help my advancement of knowledge. This is not a book to read from cover-to-cover, but best read as the requirements arise. I think the author was particularly biased towards 'pro-Cisco'. I did not see any mention of the performance degradations that can accompany MPLS implementations. Also, I think the book needed a 2nd grammatical editor, as the overall 'flow' of the book was nonevident.
