Appendix I. Practice for Chapter 21: Route Summarization

This appendix includes two features. First, it contains extra practice problems and answers related to Chapter 21, “Route Summarization,” specifically about how to summarize routes. The second feature shows how to summarize routes using binary, as promised in Chapter 21, in case you want to understand what happens in binary when you summarize routes.

Note that you can find additional practice at the author’s CCNA blog, which is linked from the author’s website, www.certskills.com.
