Using VPP with TRex Mixed Traffic Templates
===========================================
In this example, a more complicated traffic with delay profile on *net2s22c05* is
generated using the traffic configuration file "avl/sfr_delay_10_1g.yaml":
.. code-block:: console
NET2S22C05$ sudo ./t-rex-64 -f avl/sfr_delay_10_1g.yaml -c 2 -m 20 -d 100 -l 1000

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