100 Chapter 4: Network Integration and Interception

The IOS WCCPv2 conﬁguration involves two steps. First, the WCCPv2 services are

conﬁgured in global conﬁguration mode. The WCCPv2 services in IOS are conﬁgured

using the numeric service ID, as opposed to the service name used on the WAAS

conﬁguration. Example 4-15 shows the tcp-promiscuous services conﬁgured in IOS.

The second step involves conﬁguring WCCPv2 redirection on each interface through which

client and server data passes. Unless you are using the WCCPv2 negotiated return egress

method discussed later in this chapter, WCCPv2 redirection should never be conﬁgured on

the interface connecting to the WAE. Interception is conﬁgured in either the inbound or

outbound direction. When using outbound redirection, the ip wccp redirect exclude in

command must be conﬁgured in the interface connecting to the WAE. This prevents trafﬁc

coming into the WCCPv2 server (router) from being re-intercepted, which would cause a

redirection loop. Example 4-16 demonstrates a complete IOS WCCPv2 conﬁguration,

including the use of the ip wccp redirect exclude in command.
