Apparatus in one example comprises network controller(s) that serve to communicatively couple first network component with second network component. The first network component sends signaling message for the second network component to one or more of the network controller(s). The signaling message comprises indication of specific network connection(s) usable by the first network component. One or more of the network controller(s) serve to replace the indication of the specific network connection(s) usable by the first network component in the signaling message with wild card network connection information. The one or more of the network controller(s) serve to send the signaling message that comprises the wild card network connection information to the second network component. The wild card network connection information indicates the second network component is allowed to indicate to one or more of the network controller(s) specific network connection(s) usable by the second network component.
