Question : How do I provide Dhcp services for a superscoped subnet so that any host on the single broadcast domain knows to communicate on the sinlge domain without routing ?

I want to set up a superscope on a single section of 'wire' on my network using the IP ranges 10,0,1,0 and 10,0,2,0 and I'm not exactly sure how to make this work.
  Could someone please explain the following issues:

 #1) If I connected two different routers (both BOOTP/DHCP enabled)  to this section and applied IP addresses of 10,0,1,1 and 10,0,2,1 to their respective interfaces together with a subnet mask of 255,255,252,0 would this allow hosts from the two different IP ranges to know they are on the same subnet and so (not route) just shout out their message?   Also, are there any other settings/etc that I should look out for to ensure this layout fucntions properly?

#2)  I think I read somewhere on this site's archives that it is possible to attach two IP addresses to the same interface (or NIC?) on a single router (again BOOTP/DHCP enabled)attached to this section of wire with everything else as in #1 above and have it succeed. Is this possible?  If so, why would anyone use two routers?

    I seek any clear answer that decides this issue.

   Thanks

The 10.0.1.10 would determine that 192.68.1.20 is on a different network and forward the packet to it's default gateway. The router would receive the packet and forward it back out the same interface to the 192.68.1.20 device.

Not the most efficient way to move packets, is it? :-)
