Detailed explanation-1: -1. How is an EUI-64 format interface ID created from a 48-bit MAC address? D. The modified EUI-64 format interface identify is drived from the 48-bit link-layer (MAC) address by inserting the hexadecimal number FFFE between the upper 3 bytes (OUI field) and the lower 3 bytes (serial number) of the link layer address.
Detailed explanation-2: -To convert a MAC-48 into an EUI-64, copy the OUI, append the two octets FF-FF and then copy the organization-specified extension identifier. To convert an EUI-48 into an EUI-64, the same process is used, but the sequence inserted is FF-FE. In both cases, the process can be trivially reversed when necessary.
Detailed explanation-3: -EUI-64 (Extended Unique Identifier) is a method we can use to automatically configure IPv6 host addresses. An IPv6 device will use the MAC address of its interface to generate a unique 64-bit interface ID. However, a MAC address is 48 bit and the interface ID is 64 bit.
