Complete Example for Creating a Virtual Network

This section contains a complete set of commands for configuring a virtual network.

Example 11–6 Basic Virtual Network

This example shows how to implement the virtual network scenario shown in Figure 10–1. The example elaborates on the tasks presented in Configuring a Basic Virtual Network. The commands do the following:

Configure two VNICs, vnic1 and vnic2 on the data link e1000g0.
Configure two exclusive IP zones, zone1 and zone2.

Note –
The example shows only the steps to configure zone1. Repeat the same steps to create and configure zone2.
Assign automatically configured MAC addresses to each VNIC.
Set two static IP addresses for the zones and VNICs, 192.168.3.20 and 192.168.3.22.

Note –
You must log in to the system's global zone as superuser or equivalent role to run the next commands.

# zoneadm -z zone1 verify
WARNING: /export/home/zone1 does not exist, so it could not be verified.
When 'zoneadm install' is run, 'install' will try to create
/export/home/zone1, and 'verify' will be tried again,
but the 'verify' may fail if:
the parent directory of /export/home/zone1 is group- or other-writable
or
/export/home/zone1 overlaps with any other installed zones.

# zoneadm -z zone1 install
Preparing to install zone <zone1>.

Zone <zone1> is initialized.

After you repeat the same steps to create zone2 and to assign vnic2 to zone2, the following example shows you how to verify that the two zones are properly configured with their respective VNICs.
