What would be the interface ID of an IPv6 enabled interface with a MAC address of 1C-6F-65-C2-BD-F8 when the interface ID is generated by using the EUI-64 process?
1C-6D-65-FF-FE-C2-BD-F8
To determine the interface ID of an IPv6 enabled interface using the EUI-64 process, follow these steps:
1. Start with the MAC address: 1C-6F-65-C2-BD-F8
2. Split the MAC address in half: 1C-6F-65 and C2-BD-F8.
3. Insert “FFFE” in the middle: 1C-6F-65-FF-FE-C2-BD-F8.
4. Invert the 7th bit (counting from the left) of the first half: 1C-6D-65-FF-FE-C2-BD-F8.
5. Combine the modified first half and the second half: 1C-6D-65-FF-FE-C2-BD-F8.
6. Add the IPv6 prefix (usually the first 64 bits): This will depend on your network configuration or assignment.
The resulting interface ID generated using the EUI-64 process, based on the given MAC address (1C-6F-65-C2-BD-F8), would be 1C-6D-65-FF-FE-C2-BD-F8.
Remember that the IPv6 interface ID is only a part of the complete IPv6 address, and the interface ID combined with the network prefix forms the complete address. The network prefix will vary depending on your network setup or provider.
