Cisco ASR 1000 Series Configuration Guide

Registering a Router to a Multicast Address for WCCPv2— IPv6
If you decide to use the multicast address option for your service group, you must configure the router to
listen for the multicast broadcasts on an interface.
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 ipv6 multicast-routing global configuration command.
•
Enable the interfaces to which the cache engines will connect to receive multicast transmissions using
the ipv6 wccp group-listen interface configuration command.
