ip wccp
The ip wccp {web-cache | service-number} group-list command syntax resembles the ip wccp
Note
{web-cache | service-number} group-listen command, but these are entirely different commands. The
ip wccp group-listen command is an interface configuration command used to configure an interface to
listen for multicast notifications from a cache cluster. Refer to the description of the ip wccp
group-listen command in the
ip wccp
This option instructs the router to use MD5 authentication on the messages received from the service
group specified by the service name given. Use this form of the command to set the password on the
router. You must also configure the same password separately on each web cache. The password can be
up to a maximum of eight characters. Messages that do not authenticate when authentication is enabled
on the router are discarded. The default is for no authentication password to be configured and for
authentication to be disabled.
Examples The following example shows how to configure a router to run WCCP reverse-proxy service, using the
multicast address of 239.0.0.0:
Router(config)# ip multicast-routing
Router(config)# ip wccp 99 group-address 239.0.0.0
Router(config)# interface gigabitethernet 3/1
Router(config-if)# ip wccp 99 group-listen
The following example shows how to configure a router to redirect web-related packets without a
destination of 10.168.196.51 to the web cache:
Router(config)# access-list 100 deny ip any host 10.168.196.51
Router(config)# access-list 100 permit ip any any
Router(config)# ip wccp web-cache redirect-list 100
Router(config)# interface gigabitethernet 3/2
Router(config-if)# ip wccp web-cache redirect out
