Cisco ASR 1000 Series Configuration Guide

CHAPTER 3
Configuring WCCP
The Web Cache Communication Protocol (WCCP) is a Cisco-developed content-routing technology that
intercepts IP packets and redirects those packets to a destination other than that specified in the IP packet.
Typically the packets are redirected from their destination web server on the Internet to a content engine that
is local to the client. In some WCCP deployment scenarios, redirection of traffic may also be required from
the web server to the client. WCCP enables you to integrate content engines into your network infrastructure.
Cisco IOS Release 12.1 and later releases allow the use of either WCCP Version 1 (WCCPv1) or Version
2 (WCCPv2).
The tasks in this document assume that you have already configured content engines on your network. For
specific information on hardware and network planning associated with Cisco Content Engines and WCCP,
see the Cisco Content Engines documentation at the following URL:
