I have many DHCP servers in different subnets. They provide ip using mac-bindness. I wanted to centralize my DHCP servers. I configured router to be a DHCP relay agent using cisco 3750 layer 3 using " ip helper-address <dhcp address> " stuff. Now I am not being able to mac-bind the ips of another subnet, because the dhcp server in the another end is receving only the router's interface as source mac id. How to infiltrate the mac-addresses of one subnet into another so that i can mac bind the ips in my DHCP server located in another subnet ???
Thanks in advance,
