Hi @210094010
I will answer in English and you can use the translator as I did.
The hosts (PCs) need to be on the same network as the Router´s interface. For example, PC0 have IP address 10.2.11.2 and gateway 10.2.11.1. Then, the Router´s interface where the switch connects need to be 10.2.11.1. This is true for both sides of the network. PCs and gateway needs to be on the same network.
And you need Route. The Router0 does not know about the networks that is behind the Router1. The same way Router1 does not know about networks that is behind Router0. You need to tell them and you do that by using routes.
On Router0:
ip route 0.0.0.0 0.0.0.0 30.2.13.1
On Router1
ip route 0.0.0.0 0.0.0.0 30.2.13.2
Meaning, everything you dont know, send to the other router.
Look the file I attached.
