To allow a router to forward DHCPDISCOVER messages from a client to a remote DHCP server, what must be configured?

A DHCP Relay Agent is necessary because DHCPDISCOVER messages are broadcast messages, and routers, by default, do not forward broadcast traffic between different subnets. The relay agent, configured on the router interface connected to the client's subnet, captures these broadcasts and unicasts them to the specified DHCP server on a different subnet. The server's response is then unicast back to the relay agent, which forwards it to the client. DHCP Binding refers to the mapping of an IP address to a MAC address, typically maintained by the DHCP server, not a router configuration for forwarding. DHCP Snooping is a security feature that prevents unauthorized DHCP servers and malicious DHCP messages, not a forwarding mechanism. A DHCP Pool is a range of IP addresses available for assignment by a DHCP server, not a router configuration for relaying.
