Summary

This chapter provided a detailed examination of the various methods for integrating WAAS

into the network infrastructure. The chapter reviewed the various techniques for physical

connectivity, including options for increased interface bandwidth and high availability. The

chapter also previewed the network interception techniques that are used to transparently

redirect trafﬁc to the WAAS infrastructure for optimization. Particular focus was given to

WCCPv2 and inline interception, which are the two most common interception methods.

The interception method you choose is a site-local decision. For example, you can use

WCCPv2 at some locations and inline at other locations. Finally, the chapter discussed the

different egress methods available in WAAS, which provide control over how trafﬁc on

intercepted connections is reinserted into the network after redirection to a WAE. You

should now have a good feel for the ﬂexibility of the WAAS solution when it comes to

network integration. The techniques available allow Cisco WAAS to integrate into network

infrastructures of any size and complexity. The next chapter begins to put these various

techniques to use, as you look at speciﬁc deployment models for the branch ofﬁce

environment.
