Good - but not nearly as good as it should be
on May 24, 2011
Many of the explanations are rushed, vague and inconclusive. Instead of explaining command syntax the text often relies on examples extracted from show running-config output that fall short of illustrating the options in the commands. Have the CCNA Portable Command Guide handy, though that text, also, has strange ommissions. What I've ended up doing is to rely on the ICND2 cert guide as a framework for my studies while bouncing between it, the ccna portable command guide, and the CCNP ROUTE and SWITCH foundation learning guides, as well as frequent use of google to find the hard-core Cisco docs online. THIS BOOK SHOULB BE MORE COMPLETE. Seriously: there's no reason on earth to write a study guide that doesn't contain what's needed.
One more thing: Odom and Cisco Press ought to have had this run past a competent technical editor. Here's some typical bad language: "The information that correlates to the next-hop router's Layer 3 address, and the Layer 2 address used to reach it, is called mapping." While that's true, in a tortured way, it couldn't have been said much more badly. No one edited this stuff. Here's a simple principle: the language should make understanding easier, not harder. A mess like the one I just quoted makes it all much harder.
There are outright errors that will be confusing for someone learning the material for the first time. Here's the first example of an IPv6 address from chapter 17: "2340:1111:AAAA:0001:1234:5678:9ABC" A little short, no?
This book amounts to a skeleton outline with SOME successful explanations and examples. As such it's not a bad thing to organize your studies around. But wading through it is a LOT more work than it should be: the difficulty of the material doesn't justify the difficulty of reading it. The difficulty of working around the mistakes is considerable.
