Which of the following statements regarding multicast MAC addresses are false?
A.
One multicast MAC address maps to 32 multicast IP addresses.
B.
One multicast MAC address maps to only one multicast IP address.
C.
The high 24 bits of the multicast MAC address are 0x01005E, the 25th bit is fixed to 1, and the lower 23 bits of the MAC address map to the lower 23 bits of the multicast IP address.
D.
A multicast MAC address identifies receivers of a multicast group on the data link layer.
One multicast MAC address maps to 32 multicast IP addresses due to the limited number of bits used in the mapping process. Specifically, the lower 23 bits of the MAC address map to the lower 23 bits of the multicast IP address, while the high 24 bits of the MAC address are fixed as 0x01005E. Thus, Option B is false .
