I've now browsed chapters 2-5 Chap 2 - LAN protocols - tells you everything you were afraid to ask about the raw protocols historical tables. cable types, frame types, IEEE references. Let's call this the "Priscilla" chapter ;->
also covers bridging and switching in good detail. I read with great interest the section on token ring switching, and found it to be the best guide I have seen with regards to both the theory and the practical configuration of a 3920 switch. I say this with confidence because the recommendations are very close to what I developed independently, using Cisco documentation and the 3920 simulator which I believe NLI is now selling. Confidence because not too long ago I was someplace where this was important, and everything worked the way it was supposed to on the 3920, at least. superior IMHO to the very good explanation found in the Kennedy Clark book. Chap 3 WAN HDLC - OK Chap 4 WAN PPP - not too bad. concentrates on ISDN / dial. The section on PPP multilink is incredibly poor, to the point of being useless. this surprised me, as there is so much detail elsewhere. Chap 5 - frame relay. another decent chapter. contains a HUGE error. states that frame relay split horizon is on by default, and that you have to disable it manually. not true, and the source of woe to many who find themselves frustrated with certain sections of various practice labs. on a frame relay interface, split horizon is DISabled by default. several CCIEs otta be ashamed of themselves for letting that one through! ;-> The several lab exercises at the ends of each chapter cover the fundamentals pretty well. They are not necessarily CCIE level labs, but they are certainly worth looking at. So far, what I would say, is that the book contains a lot of good reference information, some good practical configuration information, and some decent exercises for all levels. I continue to recommend this one as something folks new to the field, or just starting out in the certification grid, plan on adding to their libraries. Along with the books by Doyle and Caslow, this is one that can serve well throughout the journey.
