Quick bridging Question

I have the following setup:

[ Router 1]---------(ethernet cable)------------[Router 2]=========(wifi)======

I want to bridge router 1’s and router 2’s ethernet NIC’s so that the wifi/radio of router 2 is virtually part of router 1. I don’t really understand routing, so if someone can just tell me which type of routing to look at, i can figure it out.

Thx

You can have a IP from Same subnet

Router1(eth2-192.168.1.1/24)–>>Router2(ether2-192.168.1.2/24)
Now configure bridge connectivity between ether & wlan Port in Router2.
