DHCP relay agent is used to forward DHCP messages from one network segment to another. When a DHCP client broadcasts a DHCP discovery message to find a DHCP server, the message is not forwarded across different network segments by default. The DHCP relay agent receives the DHCP discovery message and forwards it to one or more DHCP servers on different network segments.
The server-ip parameter is used to specify the IP address of the DHCP server to which the DHCP relay agent forwards the DHCP messages. This parameter is used in the configuration of the DHCP relay agent to specify the IP address of the DHCP server to which the client requests should be forwarded.
