Reserved addresses excluded from IP multicast filtering

Traffic to IP multicast groups in the IP address range of to 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.

In IP mode, nonreserved multicast IP addresses are not displayed as "reserved" addresses.
