Conclusion

This chapter covered the important steps necessary for an ISP to set up its initial router configuration correctly. It discussed the importance of the loopback interface, how to configure interfaces, as well as how to set up CEF and NetFlow. Nagle also was covered, and the chapter concluded with a discussion on how an ISP uses DNS for the network backbone infrastructure.

Combining this chapter with Chapter 1, the ISP now should have a workable router configuration ready for configuring routing protocols and the security features necessary for any ISP backbone.
