"multicast address" in this range, the switch will use the static filter unless IGMP learns of a multicast
group destination in this range. In this case, IGMP dynamically takes over the filtering function for
the multicast destination addresses for as long as the IGMP group is active. If the IGMP group
subsequently deactivates, the switch returns filtering control to the static filter.
Reserved addresses excluded from IP multicast filtering
Traffic to IP multicast groups in the IP address range of 224.0.0.0 to 224.0.0.255 will always be
flooded because addresses in this range are "well known" or "reserved" addresses. Thus, if IP
multicast is enabled, and there is an IP multicast group within the reserved address range, traffic
to that group will be flooded instead of filtered by the switch.
