+LXC/DRC Container Memif
+-----------------------
+
+|csit-release| includes tests taking advantage of VPP memif virtual
+interface (shared memory interface) to interconnect VPP running in
+Containers. VPP vswitch instance runs in bare-metal user-mode handling
+NIC interfaces and connecting over memif (Slave side) to VPPs running in
+:abbr:`Linux Container (LXC)` or in Docker Container (DRC) configured
+with memif (Master side). LXCs and DRCs run in a priviliged mode with
+VPP data plane worker threads pinned to dedicated physical CPU cores per
+usual CSIT practice. All VPP instances run the same version of software.
+This test topology is equivalent to existing tests with vhost-user and
+VMs as described earlier in :ref:`tested_logical_topologies`.
+
+In addition to above vswitch tests, a single memif interface test is
+executed. It runs in a simple topology of two VPP container instances
+connected over memif interface in order to verify standalone memif
+interface performance.
+
+More information about CSIT LXC and DRC setup and control is available
+in :ref:`container_orchestration_in_csit`.
