Excluding Multicast Addresses from IP Multicast Filtering

Excluding Multicast Addresses from IP Multicast Filtering

Each multicast host group is identified by a single IP address in the range of

224.0.0.0through 239.255.255.255. Specific groups of consecutive addresses in this range are termed “well-known” addresses and are reserved for predefined host groups. IGMP does not filter these addresses, so any packets the switch receives for such addresses are flooded out all ports assigned to the VLAN on which they were received (except the port on which the packets entered the VLAN).

The following table lists the 32 well-known address groups (8192 total addresses) that IGMP does not filter on the switches covered in this guide, as well as on the 1600M, 2400M, 2424M, 2650M, 4000M, 6108M, 8000M, and Switch 2500 Series devices.
