+    In OpenDaylight, a config parameter is available to enable DSCP
+    marking inheritance for packets egressing out of OVS through
+    VXLAN/GRE tunnels. Add a flag "OpenDaylightInheritDSCPMarking" in
+    TripleO to enable this parameter via puppet-opendaylight. If the
+    flag is set to 'true', DSCP marking feature is enabled in
+    OpenDaylight.
