How to combine two different routers into one local network?

Question

Computer networks

Hello, there are two routers, one Huawei HG8245H router and another Mikrotik hAP ac² router. The connection scheme is as follows: The ISP cable is connected to the optical port of the Huawei HG8245H router, and Mikrotik hAP ac² is connected to the LAN port of this router. Huawei HG8245H has a network of 192.168.100.1, and Mikrotik hAP ac² has a network of 192.168.88.1 I need to combine 2 networks into one local network. For example, on a computer in the Mikrotik network, I share films and on the network 192.168.100.1 you need to have access to these films. Please tell me how to do it? Thanks in advance.

Answer 1

unplug the huawei cable from the mikrotik WAN port and connect it to the LAN port (mikrotik).
Disable the DHCP server in Mikrotik.
Now Mikrotik will work as a regular switch.

Answer 2

Throw away Huawei HG8245H, buy a media converter for 2000 rubles D-Link DMC-F02SC DMC-F02SC and your Mikrotik hAP ac² is connected to it, and since the media converter is an l2 device, it will be the same as the ethernet
media converter, this is an optical signal converter to ethernet, that is, rg45
Actually why I recommend throwing out Huawei HG8245H plus crooked Chinese firmware in which you can forget about ipv6
