A virtual interfaces configuration may be represented by Objects representing the virtual and the physical network interface instances. References point from the Object(s) representing the virtual interface(s) to the Object representing the physical interface. All Objects implement the IIetfBaseNetworkInterfaceType. An example is shown in Figure A-1.

Note: The usage of the References is following the YANG modelling approach which is using reference pointers in the YANG-interface nodes to point to other interface nodes in lower or higher layers (“higher-layer-if”, “lower-layer-if”).

A link aggregation configuration may be represented by Objects representing the logical aggregation and the particular physical interface instances. References point from the Object(s) representing the aggregation interface to the Objects representing the physical interfaces. All Objects implement the IIetfBaseNetworkInterfaceType. An example is shown in Figure A-2.
