the Relay Agent domain and allocates an IP address to the DHCP Client that is in the
same subnet as the IP address in accordance with the domain value. This means that
the allocated IP address and the IP address of the interface through which Relay receives
request messages are in the same network segment. At the same time, DHCP Relay
implements the forwarding of the responses from the DHCP Server to the Client.
Configuring the DHCP Relay
