how to connect i2c

Good morning,
for my project I have to connect 10 industruino (for now I have bought two to test the system) of which one master and the other slaves. I wanted to connect them with i2c.
I have seen that the SDA and SCL outputs are the D2 and D3 of the expansion port. How can I connect? do you have an example of a sketch?
I also have two ethernet modules
thank you
