For both of the labs I took, there was only a few books I read in their entirety in preparation for them... Three actually in all. For the R&S, it was Williamson's multicast book from Cisco Press, and also Kozierok's TCP/IP Guide (which is available free: Welcome to The TCP/IP Guide!). I used other books in parts and pieces like Doyle's books, but I did not sit and necessarily study them end to end. Throughput SP preparation I used MPLS-Enabled Applications by Minei and Lucek. Also not a Cisco Press book. But, this book is hands-down the best MPLS book I have ever read.
