Registering a Router to a Multicast Address
For network configurations where redirected traffic needs to traverse an intervening router, the router being
traversed must be configured to perform IP multicast routing. You must configure the following two components
to enable traversal over an intervening router:
• Enable IP multicast routing using the ip multicast-routing global configuration command.
• Enable the interfaces to which the cache engines will connect to receive multicast transmissions using
SUMMARY STEPS
1. enable
2. configure terminal
3. ip multicast-routing [vrf vrf-name] [distributed]
4. ip wccp [vrf vrf-name] {web-cache | service-number} group-address multicast-address
5. interface type number
6. ip pim {sparse-mode | sparse-dense-mode | dense-mode [proxy-register {list access-list | route-map
map-name}]}
7. ip wccp [vrf vrf-name] {web-cache | service-number} group-listen
