Well, I do not know if you guys read my first comments on the books but I was not too thrilled about these first few chapters. Chapt 2 and 3 are not very strong on presentation and content. Check archives for earlier comments To add to comments about chapt 3: There is a Command review on IGRP on page 80 which is good but somewhat not very well explained with the context of the chapter???????????? Left me perplexed anyway! Chapter 4 is a IPv4 review: subnetting, CIDR, ip helper address, ip unnumbered etc This chapter is well presented, so worth reading, but what I don't really understand is why the authors assume that you know what the exact syntax of a command "replacements" are? Let me explain with an example: Routerc(config)# ip unnumbered <donor interface id> Seems pretty straight forward. But what I like is that it should be reinforced with perhaps a diagram with proper interface naming and complete with a concrete example. I call it a sample configuration!!!!!!! Chapt 5 and 6: Very good intro to OSPF follow by very good descriptions of output commands. Now we are talking Mr. Thomas. Of course I have to comment on the commands that have the "syntax description" only rather than a real sample configuration. These are STUDY GUIDES. I am learning the stuff so please do not "assume" that I know it because I sure don't. I expected a list of commands as per page 80 at end of chapter 3, but NOOOOOOOOO. What happen to standard writing between chapters? Doesn't this make it a better flow and answers readers expectation? Any comments are welcome.
