| VPP sends a DHCP DISCOVER
| | [Documentation] | Configure DHCP client on interface to TG without hostname
| | ...             | and check if DHCP DISCOVER message contains all required
| | ...             | fields with expected values.

| |       ... | ${nodes['TG']} | ${nodes['DUT1']} | ${nodes['TG']}
| | And   Interfaces in 2-node path are up
| | When  Set DHCP client on Interface | ${dut_node} | ${dut_to_tg_if1}
