How to Reconfigure a Zone to Use a VNIC

Language:

This procedure refers to the second zone in the virtual network. This zone already exists but its current configuration prevents it from becoming a part of the virtual network. Specifically, the zone's IP type is a shared type and its current interface is net0. Both of these configurations must be changed.

Become an administrator.

Create the VNIC.
```
global# dladm create-vnic -l link VNIC
```
You will configure the VNIC's interface later in this procedure.

Change the zone's IP type from shared to exclusive.

global# zonecfg -z zone
zonecfg:zone> set ip-type=exclusive

Change the zone's interface to use a VNIC.

zonecfg:zone> remove net physical=NIC
zonecfg:zone> add net
zonecfg:zone:net> set physical=VNIC
zonecfg:zone:net> end

Verify and commit the changes that you have implemented and then exit the zone.
```
zonecfg:zone> verify
zonecfg:zone> commit
zonecfg:zone> exit
```
Reboot the zone.
```
global# zoneadm -z zone reboot
```
Log in to the zone.
```
global# zlogin zone
```
In the zone, create an IP interface over the VNIC that is now assigned to the zone.
```
zone# ipadm create-ip interface
```
Configure the VNIC with a static IP address or a Dynamic Host Configuration Protocol (DHCP) IP address.
- Assign a static IP address.
```
zone# ipadm create-addr -a address interface
```
  –a address
  
  Specifies the IP address, which can be in CIDR notation.
- Assign a DHCP IP address.
```
zone# ipadm create-addr -T dhcp interface
```
Exit the zone.
```
zone# exit
```
From the global zone, add the address information to the /etc/hosts file.

Example 7 Reconfiguring a Zone to Use a VNIC

In this example, zone2 already exists as a shared zone. The zone also uses the primary interface of the system rather than a virtual link. You need to modify zone2 to use vnic2. To use vnic2, zone2's IP type must first be changed to exclusive. Note that some of the output is truncated to focus on the relevant information that relates to virtual networks.

global# dladm create-vnic -l net0 vnic2

global# zonecfg -z zone2
zonecfg:zone2> set ip-type=exclusive
zonecfg:zone2> remove net physical=net0
zonecfg:zone2> add net
zonecfg:zone2:net> set physical=vnic2
zonecfg:zone2:net> end
zonecfg:zone2> verify
zonecfg:zone2> commit
zonecfg:zone2> exit
global# zoneadm -z zone2 reboot

global# zlogin zone2
zone2# ipadm create-ip vnic2
zone2# ipadm create-addr -a 192.0.2.85/24 vnic2
ipadm: vnic2/v4

zone2# exit

global# pfedit /etc/hosts
#
::1             localhost
127.0.0.1       localhost
192.0.2.20    loghost   #For net0
192.0.2.80    zone1   #using vnic1
192.0.2.85    zone2   #using vnic2
