Interception Techniques and Protocols 99

Example 4-12 shows a basic WCCP router list conﬁguration.

Up to six IP addresses may be deﬁned per line. For deployments where there are more than

six routers in the service group, additional router IP addresses can be deﬁned by conﬁguring

a second line using the same router list number. Example 4-13 shows a WCCPv2 router list

conﬁgured with ten IP addresses.

CAUTION Do not use virtual IP (VIP) addresses, such as an HSRP virtual IP address, in the WCCPv2

router list. The router list should contain only interface IP addresses. When the WAE is L2

adjacent to the WCCP-enabled router(s), the IP address(es) used in the WCCP router list

should be the directly connected interface IP addresses. In cases where the WAE is not L2

adjacent to the WCCP-enabled router(s) (that is, the WAE is multiple L3 hops away from

the WCCP-enabled router or routers), a loopback interface IP address should be used in the

router list conﬁguration. Using a loopback interface IP address improves the reliability of

the WCCP service group, because the loopback interface IP address is not tied to the

availability of any single physical interface.

For the second step, the WCCPv2 tcp-promiscuous service is conﬁgured and associated

with the router list created in the ﬁrst step. The following command syntax is used:

wccp tcp-promiscuous router-list-num 1

The ﬁnal conﬁguration step is to enable WCCPv2 using the command wccp version 2. This

command starts the WCCPv2 negotiation with any IOS devices conﬁgured in the router list.

Example 4-14 shows a complete WCCPv2 conﬁguration in Cisco WAAS.
