Three interfaces on the same network

I want three interfaces on the same network.

For separate networks I know how it works but on the same network, the route
seems wrong.

It takes the first interface as default an thats the only card that is working.

How do I configure the interfaces file?

    Presumably the desire for three interfaces on the same network is increased bandwidth or availability. That can be done, but not by simply attaching each of the NICs to the same network. You'll need to configure a bonding interface and make these NIC a part of it (see the networking/bonding.txt in the kernel documentation). And you'll need to be connecting to a switch that's compatible with the Linux bonding driver.

    The alternative to bonding the NICs is to use trunking capable NIC's and create a 3x VLAN trunk to a compatible switch.
