Activate DHCP Relay Mode for a Routed Network backed by NSX in the VMware Cloud Director Tenant Portal

Starting with VMware Cloud Director 10.3.1, you can add a DHCP relay to an NSX edge gateway that is associated with your organization VDC network.

In DHCP Relay mode, when a guest OS transmits a DHCP request for an IP address and related metadata, the NSX edge gateway receives the request and relays it to a designated DHCP server in your physical DHCP infrastructure as a unicast flow. When the response is received by the relay, it is forwarded to the requesting guest OS.

Prerequisites

• Verify that you are an organization administrator, system administrator, or that you are assigned a role that includes an equivalent set of rights.

• Verify that the network for which you want to activate DHCP is routed and that an NSX edge gateway is associated with it.
• Verify that DHCP forwarding is enabled on the edge gateway. See Enable DHCP Forwarding on an NSX Edge Gateway in the VMware Cloud Director Tenant Portal.
