IGMP is disabled on the interface.

ip igmp explicit-tracking
Description
With this command, you enable die function "Explicit Tracking" on an interface.
If the "Explicit Tracking" function is enabled, the multicast router tracks precisely which
clients log on to a multicast group (Join) and log off (Leave). As soon as the last client has
logged off from a multicast group, the multicast router deleted the multicast group. Since the
multicast router has precise information about the logged on and logged off clients, the
multicast router does not need to query whether a further client wants to receive the
multicast.
