On a Cisco router interface, an IPv6 global unicast address built from the interface MAC address via the modified EUI-64 process is produced only when
Computing the EUI-64 Interface ID for a Given MAC Address
EUI-64 converts the 48-bit MAC into a 64-bit interface ID by splitting it, inserting FFFE, and inverting the seventh bit of the first byte. Here that
Building the EUI-64 Interface Identifier for Router R2
EUI-64 builds the interface ID from the MAC: split at the OUI/host boundary, insert FFFE, and flip the seventh bit (U/L) of the first byte. For R2 the
EUI-64 Interface ID Calculation for Router R2 (Segment 7)
EUI-64: split the MAC, insert FFFE, and invert the seventh bit. R2's first byte becomes C8, giving C801; the FFFE insertion gives B6FF; the host half
Forming the EUI-64 Suffix for Router R1 (Segment 8)
EUI-64 on R1's MAC: invert the seventh bit to C8 (C801), insert FFFE (B8FF), and append the host half to produce FEB3, matching option C.
Computing the IPv6 EUI-64 Interface ID from a Given MAC
EUI-64 builds the 64-bit interface ID from the 48-bit MAC: split the MAC at the OUI/host boundary, insert FFFE in the middle, and flip the seventh bit
