Usage guidelines

In a VXLAN network, the DHCP relay agent feature can be configured on the VSI interface of a VTEP.

When the DHCP relay agent receives a DHCP request from an AC mapped to the VSI interface, the relay agent forwards this request to the DHCP servers and broadcasts this request to other VTEPs. If those VTEPs also function as the DHCP relay agents, each will forward the DHCP request to the DHCP servers they are connecting to. To prevent a DHCP server from receiving the same DHCP request from different VTEPs, you can configure this command on the VSI interface of the VTEPs that are not directly connecting to DHCP clients.

Examples
