*** Test Cases ***
| VPP can push and pop two VLAN tags to traffic transferring through xconnect
| | [Documentation] | Push two tags on DUT 1 to traffic sent from TG,
| | ... | pop two tags on DUT 2 from this traffic
| | ... | and receive untagged traffic on TG.
| | ...
| | Given Path for 3-node testing is set
| | ... | ${nodes['TG']} | ${nodes['DUT1']} | ${nodes['DUT2']} | ${nodes['TG']}
| | And Interfaces in 3-node path are up
| | When VLAN subinterfaces initialized on 3-node topology
| | ... | ${dut1_node} | ${dut1_to_dut2} | ${dut2_node} | ${dut2_to_dut1} | ${subid}
| | ... | ${outer_vlan_id} | ${inner_vlan_id} | ${type_subif}
| | And L2 tag rewrite method setup on interfaces
| | ... | ${dut1_node} | ${subif_index_1} | ${dut2_node} | ${subif_index_2}
| | ... | ${tag_rewrite_method}
| | And Interfaces and VLAN sub-interfaces inter-connected using L2-xconnect
| | ... | ${dut1_node} | ${dut1_to_tg} | ${subif_index_1}
| | ... | ${dut2_node} | ${dut2_to_tg} | ${subif_index_2}
| | Then Send and receive ICMP Packet
| | ... | ${tg_node} | ${tg_to_dut1} | ${tg_to_dut2}
