DHCP Superscope IP Helper

Hello,

Our 10.1.2.X subnet has depleted all available IP addresses. I created a secondary IP on our 1841 router (IOS 12.4) of 10.1.6.X. I?m going to create a superscope on our Win2k DHCP server (10.1.2.X) to distribute IP addresses from the .2.X and the .6.X subnets. I have assigned and tested a few static .6.X addresses and they seem to work fine.

Do I need to add an IP Helper command to have the DHCP broadcasts from the secondary IP forwarded to the DHCP server?

Can you recommend any other things to look for or consider before implementing this?

Thanks,
Joel
