Building Virtual Networks
You can configure more than one VNIC on a physical device. Thus, you can create a multinode network within a single system. The network would consist of virtual servers (zones) that are connected in a network within a single operating system instance.
The following figure shows an example of a virtual network setup in an Oracle Solaris host.
Figure 5 Virtual Network Setup
The procedures in this section are based on the following assumptions:
-
The virtual network on the system consists of three zones. The procedures in this section are based on the following zone configurations:
-
The first zone zone1 is created as a new zone with an anet resource. For information, see How to Configure a Zone for the Virtual Network.
-
The second zone zone2 already exists on the system and needs to be reconfigured to use a VNIC. For information, see How to Reconfigure a Zone to Use a VNIC.
-
The third zone zone3 already exists on the system. You need to temporarily create the VNIC zone3/v3 in zone3 from the global zone. For information, see Creating VNICs Directly for Zones.

-
The system's physical interface is configured with the IP address 192.0.2.20.
-
The router's IP address is 192.0.2.25.
When building the virtual network, some steps are performed in a global zone and some are performed in a non-global zone. For clarity, the prompts in the examples after each step indicate in which zone a specific command is issued. However, the actual path that the prompts display might vary depending on the prompts specified for your system.
