System Administration Guide: Network Interfaces and Network Virtualization

Basic Virtual Network on a Single System

Figure 10–1 shows the basic virtual network, or “network in a box” that is used in examples throughout the section Configuring a Basic Virtual Network.

Figure 10–1 Virtual Network on a Single Host

The figure is described in the following context.

This virtual network consists of the following:

The VNICs and zones in this configuration allow access to the public. Therefore, the zones can pass traffic beyond the e1000g0 interface. Likewise, users on external networks can reach applications and services offered by the zones.

Best Uses for the Basic Virtual Network

The network in a box scenario enables you to isolate processes and applications into individual virtual machines or zones on a single host. Furthermore, this scenario is expandable to include many containers, each of which could run a completely isolated set of applications. The scenario improves a system's efficiency and, by extension, the efficiency of the local network. Therefore, this scenario is ideal for the following users:
