Title: This book is filled with technical errors
Review: There are so many gross technical errors in this book that I came away convinced that it had never received a serious technical review within Cisco. If so, it would never have been published.Examples:On page. 60, the book shows an IGMP join being propagated all the way back to a video server. This isn't how IGMP works; the only feedback a video server receives is RTCP reports. It is routing protocols that handle setup of multicast routing paths within the network, not IGMP.On page 164, the authors talk about 10-megabyte and 100-megabyte Ethernet. Throughout the book, they confuse bits and bytes so often that it appears that the authors don't know the difference themselves.Looking at the author qualifications, one author is a technical writer, and the other is a marketing person. Not the kind of qualifications you'd expect from authors of a Cisco Press book.
