Mikrotik Cloud Core Router + Mikrotik Cloud Router Switch

Hi Mikrotik Forums,

I just purchased three Cloud Router Switches (CRS125-24G-1S-RM), six S-31DLC20D, and three SFP cables.

I plan on placing three of the SFP modules in my cloud core router (CCR1036-12G-4S) and the other three modules in the other three switches I just purchased.

My network is setup in three subnets. (10.1.0.1/24, 10.2.0.1/23, 10.3.0.1/23). I want each of the SFP ports on the cloud core router to be assigned to one subnet, meaning three of the four SFP ports will be in use.

On the cloud router switches, I do not need any fancy setup, as we are replacing our L2 switches with them just because they have the SFP ports and better hardware.

My question is, how can I preform this setup (as mentioned above) on my CCR and my CRS?

Thanks,

Mark
