*** Test Cases ***
| 1core VPP passes 64B frames through IPv4 forwarding at 3.5mpps in 3-node topology
| | Given IPv4 forwarding initialized in a 3-node circular topology
| | Then Traffic should pass with no loss | 10 | 3.5mpps | 64 | 3-node-IPv4

| 1core VPP passes 1518B frames through IPv4 forwarding at 10gbps in 3-node topology
| | Given IPv4 forwarding initialized in a 3-node circular topology
| | Then Traffic should pass with no loss | 10 | 10gbps | 1518 | 3-node-IPv4

| 1core VPP passes 9000B frames through IPv4 forwarding at 10gbps in 3-node topology
| | Given IPv4 forwarding initialized in a 3-node circular topology
| | Then Traffic should pass with no loss | 10 | 10gbps | 9000 | 3-node-IPv4
