I am looking at the DHCP documentation and i cannot seam to find how to configure the router to use a loopback interface as the relay-agent. My objective is to use option 82 so that the dhcp server is able to identify the pool to assign ip addresses from and use a loopback ip address as the source ip address of the DHCP request.
I know that Meraki MX routers work this way, does anyone know if this is possible on Cisco routers?
Thanks

command. Unlike what you asked in your initial question, it has nothing to do with finding the correct pool - it's used to make sure that the request come from legitimate hosts and the response comes from a legitimate DHCP server. – Jesse P. Nov 23 '20 at 12:10
