+        This configuration knob controls the insertion of 4-octet control word
+        between bottom of MPLS label stack and L2 payload.
+        Control word should be used with the value 0 (e.g., a 4-octet field
+        with a value of zero) when sending EVPN-encapsulated packets over
+        an MP2P LSP.
