| 3 | Using VPP with TRex Mixed Traffic Templates |
| 4 | =========================================== |

| 6 | In this example, a more complicated traffic with delay profile on *net2s22c05* is |
| 7 | generated using the traffic configuration file "avl/sfr_delay_10_1g.yaml": |

| 11 | NET2S22C05$ sudo ./t-rex-64 -f avl/sfr_delay_10_1g.yaml -c 2 -m 20 -d 100 -l 1000 |

| 34 | Summary |
| 35 | ======= |
| 36 | |
| 37 | This tutorial showed how to download, compile, and install the VPP binary on an |
| 38 | Intel® Architecture platform. Examples of /etc/sysctl.d/80-vpp.conf and |
| 39 | /etc/vpp/startup.conf/startup.conf configuration files were provided to get the |
| 40 | user up and running with VPP. The tutorial also illustrated how to detect and bind |
| 41 | the network interfaces to a DPDK-compatible driver. You can use the VPP CLI to assign |
| 42 | IP addresses to these interfaces and bring them up. Finally, four examples using iperf3 |
| 43 | and TRex were included, to show how VPP processes packets in batches. |
