Hello Konstantinos

You can configure your OSPF network between two routers to be a point-to-point network type. More information about this can be found in the following lesson:

> **[OSPF Network Type Point-to-Point over Frame-Relay](https://networklessons.com/ospf/ospf-network-type-point-to-point-over-frame-relay)**
>
> This lesson explains the OSPF point-to-point network type on a frame-relay network. This is one of the many network types OSPF supports.

Now the lesson describes such a network-type configuration over a Frame-Relay network. However, this can also be configured over ethernet links. And these ethernet links can be directly connected between routers, or they can indeed go over a switch.

Now, if the switch is a Layer 2 switch, it plays no part in any Layer 3 operations, such as sharing OSPF routes or routing traffic. All Layer 3 communication takes place directly between the two OSPF routers. As a result, to answer your question, you require no specialized configuration on the switch to make this operate correctly. You simply must make sure that both routers are connected to ports on the same VLAN on the switch.

I hope this has been helpful!
