• An IPv6 multicast user control policy is functionally similar to an IPv6 multicast group filter. A difference
lies in that a control policy can control both multicast joining and leaving of users based on
authentication and authorization, but a multicast group filter is configured on a port to control only
multicast joining but not leaving of users without authentication or authorization.
