How does a DHCP server give a requesting “”workstation an IP address”” if each computer (server, workstation) are on two different subnets, ??? if server and workstation are connected into one Layer 3 switch.
Thanks

Have a look at this document:
If the server and workstation are on 2 different subnets and the DHCP server is in the server subnet you need to add an ip helper-address command to the workstation vlan interface

Sorry I made a mistake. I read the rest of the link. You are right. it appears in this case a DHCP service scope would be needed for each different subnet, then the different L3 vlans can communicate. Also the DHCP relay agent would also need to be used.

This is what I used for the answer.
