Detailed explanation-1: -Explanation: The multicast MAC address is a special value that begins with 01-00-5E in hexadecimal. It allows a source device to send a packet to a group of devices.
Detailed explanation-2: -The features of an Ethernet multicast frame are as follows: It has destination MAC address 01-00-5E when the encapsulated data is an IPv4 multicast packet and destination MAC address 33-33 when the encapsulated data is an IPv6 multicast packet.
Detailed explanation-3: -A multicast MAC address identifies a group of receivers at the data link layer. As defined by IANA, the most significant 24 bits of an IPv4 multicast MAC address are 0x01005E. Bit 25 is 0, and the other 23 bits are the least significant 23 bits of a multicast IPv4 address.
