Looking Ahead

This chapter touches on several problems that can arise when redistributing routes. Avoiding or correcting trouble in all but the simplest redistribution schemes usually involves the use of route filters, which are discussed in Chapter 13, or route maps, discussed in Chapter 14. Those chapters include examples of more complex redistribution schemes and how to troubleshoot them. First, though, Chapter 12 examines default routeswhich may be thought of as the most generic form of summary routes.
