Отрывок из книги
There are many people that work to put a book together, and as an author, I dedicated an enormous amount of time to write this book, but it would have never been published without the dedicated, hard work of many other people.
Kenyon Brown, my acquisitions editor, is instrumental to my success in the world of Cisco certification. Ken, I look forward to our continued progress together in both the print and video markets!

Chapter 4: Easy Subnetting You’ll actually be able to subnet a network in your head after reading this chapter if you really want to! And you’ll find plenty of help in this chapter as long as you don’t skip the written labs and review questions at the end.
Chapter 5: VLSMs, Summarization, and Troubleshooting TCP/IP Here, you’ll find out all about variable length subnet masks (VLSMs) and how to design a network using VLSMs. This chapter will finish with summarization techniques and configurations. As with Chapter 4, plenty of help is there for you if you don’t skip the written lab and review questions.
