-Virtual Topologies
-------------------
-
-CSIT NSH_SFC functional tests are executed in VM-based virtual
-topologies created on demand using :abbr:`VIRL (Virtual Internet Routing
-Lab)` simulation platform contributed by Cisco. VIRL runs on physical
-baremetal servers hosted by LF FD.io project. All tests are executed in
-three-node virtual test topology shown in the figure below.

-SUT1 and SUT2 are two VMs (running Ubuntu or Centos, depending on the
-test suite), TG is a Traffic Generator (running Ubuntu VM). SUTs run VPP
-with nsh-plugin in Linux user-mode as a Device Under Test (DUT) within
-the VM. TG runs Scapy SW application as a packet Traffic Generator.
-Network connectivity between SUTs and to TG is provided using virtual
-NICs and VMs' virtio drivers.
