Further, there is Mikrotik, it is already according to the standard 192.168.88.0/24 The
task is to organize free access to both networks, from both networks.
So that you can freely access the Mikrotik network from the tp-link network.
From the Mikrotik network, it turns out to get into the TP-link network (it's understandable)
Thank you all for any constructive help!
