Why using "dummy" at all? Use iproute2 instead:

ip addr add IP/NET brd GW-IP dev ETH-DEV label ETH-DEV

This will add a further IP/NET with gateway set to GW-IP to existing
ethernet device ETH-DEV. You can add as much IP addresses as you like.
They don't have to be from the same net like the main IP of the ethernet
device.

The tool "ip" has much more options is more powerful than the old
ifconfig.
