+Executing GRE decapsulation tests
+---------------------------------
 
+To run GRE decapsulation tests:
+
+1. Set the variables used in "Executing Tunnel encapsulation tests"
+
+2. Set IXNET_TCL_SCRIPT, GRE_FRAME_L2, GRE_FRAME_L3 and DUT_NIC1_MAC of your settings file to:
+
+  .. code-block:: console
+
+   IXNET_TCL_SCRIPT='ixnetrfc2544v2.tcl'
+
+   GRE_FRAME_L2 = {'srcmac':
+                   '01:02:03:04:05:06',
+                   'dstmac':
+                   '<DUT's NIC2 MAC>',
+                  }
+
+   GRE_FRAME_L3 = {'proto': 'gre',
+                   'packetsize': 64,
+                   'srcip': '1.1.1.1',
+                   'dstip': '192.168.240.1',
+                  }
+
+   GRE_FRAME_L4 = {'srcport': 0,
+                   'dstport': 0
+                   'inner_srcmac': '01:02:03:04:05:06',
+                   'inner_dstmac': '06:05:04:03:02:01',
+                   'inner_srcip': '192.168.0.10',
+                   'inner_dstip': '192.168.240.9',
+                   'inner_proto': 'udp',
+                   'inner_srcport': 3000,
+                   'inner_dstport': 3001,
+                  }
+
+    # The receiving NIC of GRE traffic
+    DUT_NIC1_MAC = '<mac address>'
