Two networks thru Layer 2 that doesn't allow vlans

RouterOS General
1

I have a 500Mb layer 2 circuit from an ISP that isn’t allowed to transmit VLANS
I have two different networks which I need to transit thru the L2 circuit via two different transit IP’s
network 1 via 10.73.75.0/30
network 2 via 10.75.75.0/30

I have a ccr2004-16g-2s+ and so what is the best way to achieve this?

You really have not given us enough information to formulate a helpful response. But in general I would introduce you to the “router”, the router was created from the soul need of connecting layer 2 networks together.
