When transferring an export between MikroTik routers, which information should be removed?

• A. MAC Addresses
• B. IP Addresses
• C. Hostnames
• D. Subnet Masks

Answer: (A)

MAC addresses are hardware-specific identifiers tied to each router’s network interfaces. When you export a configuration and then apply it to a different MikroTik device, keeping those explicit MAC-address lines would try to fix each interface to the original device’s hardware address. That can cause mismatches or conflicts on the new router, since its NICs have their own legitimate MACs. By removing the MAC-address assignments from the export script, the router will automatically use its own MAC addresses for its interfaces, avoiding any conflicts and ensuring the configuration binds to the correct hardware.

Other items like IP addresses, hostnames, and subnet masks aren’t tied to the specific hardware in the same way and can be adjusted later to fit the new network, so there’s no need to remove them for a transfer.
