Introduction

This chapter demonstrates how to properly configure the advanced technologies introduced in chapter 8. It will become a great reference tool to use when you are ready to configure these technologies on your network, and thus, as far as possible, every effort has been made to afford complete coverage of advanced technologies configurations. It is not feasible, however, to show all of the options available with these mechanisms.

In the last chapter, we introduced these advanced mechanisms and mentioned that they are typically far more versatile when used in combination with other QoS techniques. In this chapter, we show you how these mechanisms can be used alone, as well as how powerful they can be when combined with other techniques.

There will be things that you want to do with these QoS mechanisms that we do not show you. Thus, you should become familiar with Cisco s Web site (www.cisco.com). The pages of CCO (Cisco Connection Online) contain more information than any book could ever hope to have, and this resource is kept up to date with the most cutting edge technologies and uses for existing technologies.

Enabling, Verifying, and Troubleshooting Resource Reservation Protocol (RSVP)

In Chapter 8, we learned that RSVP guarantees QoS to applications by reserving resources on the router. Specifically, two types of services can be guaranteed. To provide controlled-load service to applications, RSVP uses WRED on the output interface in the downstream direction of the reservation. To provide guaranteed-rate service, RSVP uses WFQ on...
