For multicast forwarding, the mac addresses in the range 01-00-5E-00-00-00 to 01-00-5E-7F-FF-FF have been reserved. The most significant 25 bits of the above 48-bit mac address are fixed while the lower 23 bits are variable. These lower 23 bits are derived from the lower 23 bits of the multicast IP address. The IP multicast range spans from 224.0.0.0 to 239.255.255.255. The most significant 4 bits of this address range is fixed ( 1110 ). Hence when an IP multicast address maps to a mac address, out of the total of..... Read More
