You have been tasked with creating a dedicated virtual network between two local zones within...

Etherstubs are pseudo ethernet NICs which are managed by the system administrator. You can create VNICs over etherstubs instead of over physical links. VNICs over an etherstub become independent of the physical NICs in the system. With etherstubs, you can construct a private virtual network that is isolated both from the other virtual networks in the system and from the external network. For example, you want to create a network environment whose access is limited only to your company developers than to the network at large. Etherstubs can be used to create such an environment.

Note: Oracle Solaris 11 introduces a new and powerful network stack architecture which includes:

* Networking virtualization with virtual network interface cards (VNICs) and virtual switching (etherstubs)

* Tight integration with zones

* Network resource management - efficient and easy to manage integrated quality of service (QoS) to enforce bandwidth limit on VNICs and traffic flows
