"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.
