Configuration

Before configuring the DHCP client and the DHCP relay agent, make sure that DHCP server is configured and the dhcpd service is running in the DHCP server.

Topology

In the below example, DHCP server1 and DHCP server2 (OcNOS or Linux devices) are connected to the DHCP relay agent (an OcNOS device), and the DHCP relay is connected to a DHCP client (an OcNOS device). The DHCP client sends discover message to the DHCP servers through the DHCP relay agent.
