Chapter 36. Routing: Miscellaneous Topics

In the previous chapters, we saw how the various routing features work and how they interact with each other and with other kernel subsystems. In this chapter, we conclude the routing part of the book with a description of how the subsystem interacts with the user-space commands that configure routing. I will not describe the commands themselves, because administration is outside the scope of this book. We will also look at the various files exported in the /proc directory that can be used to tune routing. The chapter concludes with a detailed description of the data structures already introduced in Chapter 32.
