About Network Infrastructure and Virtual Local Area Networks on Oracle Database Appliance Virtualized Platform
To specify which network you want to use to access a virtual machine, you employ network infrastructure components of Oracle Database Appliance Virtualized Platform.
Oracle Database Appliance Virtualized Platform manages all of the high-level network infrastructure components for you by pre-creating the bridges for all networks. The front-end point for accessing a virtual machine is one of the bridges defined for Dom0.
The network interfaces differ, depending on your Oracle Database Appliance hardware. In all cases, connections to user domains are through the selected interfaces. Refer to the tables for your Oracle Database Appliance. Refer to the figure "Basic Virtual Machine Local Area Network" for an overview of network interface configuration.
Oracle Database Appliance Version 1 Virtualized Platform Network Interfaces
The following table lists the default network interfaces for Oracle Database Appliance Virtualized Platform on Oracle Database Appliance version 1 (systems without an external storage shelf).

Configuration Overview of Oracle Database Appliance Virtual Machine Local Area Networks
When you configure a virtual machine, you define which network the virtual machine should use by identifying the related bridge.
For example, to connect a virtual machine named myvm1 to the net1 network, you would use the following command:
oakcli modify vm myvm1 -addnetwork net1
The illustration “Basic Virtual Machine Local Area Network" shows a typical Oracle Database Appliance local area network configuration that results from this virtual machine network configuration:
Figure 3-3 Basic Virtual Machine Local Area Network
Description of "Figure 3-3 Basic Virtual Machine Local Area Network"
You assign default Virtual Local Area Networks (VLANs) to ODA_BASE during the installation and configuration of Oracle Database Appliance Virtualized Platform. The figure "Oracle Database Appliance Virtualized Platform with Virtual Local Area Networks" shows a typical Oracle Database Appliance configuration using VLANs. The illustration shows the same configuration as in "Basic Virtual Machine Local Area Networks," but with three tagged VLANs added for backups (backup), for applications (application), and for management (mgnt).
