Enable the DHCP or BOOTP relay function, using the following command: enable bootprelay {{vlan} [vlan_name] | {{vr} vr_name} | all [{vr} vr_name]}
Configure the addresses to which DHCP or BOOTP requests should be directed, using the following command: configure bootprelay add ip_address {vr vrid}

Configure the DHCP relay agent option (option 82), using the following command:
