Cisco routers and switches are the cornerstones of many networks. But when things break, repairs can intimidate even the most competent administrator. Luckily, just knowing the "in case of emergency" basics will take you far. Just like the original, this second edition of the highly acclaimed Cisco Routers for the Desperate is written for the administrator in crisis mode. Updated to cover switches and the latest Cisco terminology, with a tighter focus on the needs of the small network administrator, this second edition gives you what you need to know to provide reliable network services and fix problems fast. You'll find coverage
Cisco Routers for the Desperate, 2nd Edition is designed to be read once and left alone until something breaks. When it does, you'll have everything you need to know in one easy-to-follow guidebook.
I enjoyed reading this book however this book was suffering from some issues, first there were simply uncorrected spelling errors (RAIDUS anyone ?) which slipped through, next to this the book is not always complete (it mentions a port can be an access port but doesn't mention the alternative), it doesn't always explain all acronyms (e.g. it says to enter spanning-tree-mode pvst but doesn't explain what pvst actually means) and the selection of topics (no vlans, no trunking).
Hence the amount of information you get per page (it's not a very thick book) is interesting and if the protocols you're using happen to be the ones covered in this book you'll be happy.
