Hello. Our company is currently undergoing a network migration. One of the goals is to place two identical subnets in different locations. In one location, there will only be a server, and in the other — hosts that need to communicate with that server. Is there anyone who can help me configure this or at least outline what needs to be set up? I should also mention that the communication must take place without the use of VPN or VLAN. I just need configure Mikrotik side. Other Administrator will configure Cisco side.

An alternative (and simple) solution: a dedicate “bridge” link, bridging the two switch domains.
