CHAPTER 4
WCCPv2—IPv6 Support
This feature introduces support for Web Cache Communication Protocol version 2 (WCCPv2) in an IPv6
environment.
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.
Multiple routers can use WCCPv2 to service a content engine cluster. In WCCPv1, only one router can
redirect content requests to a cluster.
