+          NOTE:	The indication of externally-managed internal VLs is needed in case networks
+          have been pre-configured for use with certain VNFs, for instance to ensure that these
+          networks have certain properties such as security or acceleration features, or to address
+          particular network topologies. The present document assumes that externally-managed internal VLs
+          are managed by the NFVO and created towards the VIM.
