Share home router ip

I need to share my home router ip.
I have two GL.iNet GL-MT300N-V2 (OpenWRT portable wifi with ethernet) one of which should be connected to the router and the other of which will be used as a wifi hotspot should have the same IP address.
Does Zerotier fit my needs?
Thank you .

If they run ZeroTier, they will get ZeroTier IP addresses. You can try it for free, on your routers and any workstations.
