+          A link port is not needed for an external CP instance that exposes a VIP CP in the following cases:
+          1. For a VIP CP directly exposed as extCP:
+             1.1.	no dedicated IP address is allocated as VIP address, as indicated in the VNFD
+             1.2.	a dedicated IP address is allocated as VIP address, but the NFVO indicates that no port is needed
+                (createExtLinkPort in VnfExtCpConfig set to false).
+          2.	For a VIP CP exposed as extCP via a floating IP address:
+            2.1.	no dedicated IP address is allocated as VIP address, as indicated in the VNFD,
+              and the VNFC CP associated to the VIP CP is also exposed via a floating IP address.
