Hello Bahri

I assume it is this topology that you are talking about:

Essentially, the three routers are connected not as a point to point connection (obviously, since there are more than two interconnected devices), but as a multiple access network. This multiple access network can be interconnected by switches or any number of layer two devices. So in between the three routers there can indeed be a switch or any number of switches interconnecting these routers within a single subnet/network segment.

The switch was left out of the topology for simplicity’s sake…

I hope this has been helpful!
