i have two identical mikrotik routers with identical OS version, first one is configured and it is in production, and a second one is in the box if first one died. i made /export command on the first router and take that file as a backup. i read that I need to edit mac addresses in /interface ethernet with the new MAC of the second router, and another solution is to delete /interface ethernet from that .rsc file. so what would be better, edit mac addresses or deleting the all /interface ethernet section??
is there any other system stuff in .rsc file that i need to change before importing that config to another router??
Either way works fine it depends on if you have specific information like comments or port settings you want to keep. Strictly speaking you don’t “have to” edit out the MAC address, it will just then clone the MAC on those interfaces. If those two routers share the same layer2 network, that could then cause problems.
Other stuff you might want to edit depends on what packages you are using, or if it is a different OS version. If you copy and paste the text into the CLI interface, either from the terminal window or SSH, it will highlight any errors that occurred when you put on the configuration, and you can adjust it from there. Just make sure you don’t have a firewall rule that will end up breaking the connection part way through when you are uploading it.
