Explanation/Reference:
Note:
* In Oracle Solaris 11, etherstubs and VNICs are the basic components of network virtualization.
* The VNIC connects the virtual network to the external network. The VNIC also enables the zones to communicate with one another through the virtual switch that is automatically created with the VNIC. For a virtual network to host traffic internally between zones and with the external LAN and the Internet, each zone must have its own interface. Therefore, you must repeat this procedure as many times as the number of zones that will belong to the virtual network.
* Create the etherstub.
# dladm create-etherstub etherstub
Perform this step only if you are creating a private virtual network which you want to restrict from being accessed by external systems.
