Split subnet into smaller subnets with no nat

RouterOS Beginner Basics
1

Hi,

I have a few Routerboards used with simple SOHO setups, but i now have a customer who want to replace a OLD cisco.
The setup is rather simple as the cisco have a /24 subnet which is split into several smaller subnets with a small subnet on each interface.

As I’m rather new on Mikrotik i really need a bit of guidance on this setup.
I need no Firewall or NAT, just plain routing.

Thanks in advance. :slight_smile:

post your cisco config

Just do the same as on the Cisco. Assign an IP to each interface and connect devices. I asume a separate switch ia in use for L2 traffic.

Yes, each interface has a wire to seperat companies who has a router/switch connected for their internal networks.

So to define the steps i should do this:

  • Remove the default bridge and master/slave configuration along with DHCP server.
  • Configure each interface with an IP address which will act as gateway for the connected devices.
  • Set the subnet on the interface to the smaller mask E.g. /30 /29 etc.
  • Set the default route to the /24 gateway IP

Should i define any routes for the smaller subnets or do i miss anything here?

The first three points are correct.
I do not fully understand your fourth point.
Maybe you can give a brief overview of your topology
