Well, it's a few years since I played with a multi-homed DHCP server,
but I am pretty sure it went something like this:-

For eth0 with address 10.1.1.1 and eth1 on 10.1.2.1:

subnet 10.1.1.0 netmask 255.255.255.0 {
	range 10.1.1.21 10.1.1.25;
	option broadcast-address 10.1.1.255;
	option routers 10.1.1.3;
	option domain-name-servers 10.1.1.3, 10.1.1.1;
}

subnet 10.1.2.0 netmask 255.255.255.0 {
	range 10.1.2.21 10.1.2.25;
	option broadcast-address 10.1.2.255;
	option routers 10.1.2.3;
	option domain-name-servers 10.1.2.3, 10.1.2.1;
}

I also used a similar stanza to serve 10.1.3.0/24 via dhcrelay and it
all worked fine.

HTH
