`<CommonParameters>`

This cmdlet supports Microsoft PowerShell common parameters. For more information on common parameters, see [ Microsoft Docs](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_commonparameters?view=powershell-7).

## Output Object
The cmdlet returns the `VBRViVirtualLabNetworkOption` object that defines network settings of isolated networks and how to map it to production networks.

## Examples

::: example
### Example 1. Modifying Subnet Mask

This example shows how to modify a subnet mask of an isolated network that connects to the to production network.

```
$server = Get-VBRServer -Name "srv01.tech.local"
$network = Get-VBRViServerNetworkInfo -Server $server
$maprule = New-VBRViNetworkMappingRule -ProductionNetwork $network[3] -IsolatedNetworkName "Sandbox01 Private VM Network" -VLANID 5
$isolated = New-VBRViVirtualLabNetworkOptions -NetworkMappingRule $maprule -IPAddress 172.17.1.2 -SubnetMask 255.255.0.0 -MasqueradeIPAddress 172.22.22.22
Set-VBRViVirtualLabNetworkOptions -Options $isolated -SubnetMask 255.255.255.0
```

Perform the following steps:

1. Run the [`Get-VBRServer`](get-vbrserver.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$server` variable.
2. Run the [`Get-VBRViServerNetworkInfo`](get-vbrviservernetworkinfo.md) cmdlet. Set the `$server` variable as the `Server` parameter value. Save the result to the `$network` variable.
3. Run the [`New-VBRViNetworkMappingRule`](new-vbrvinetworkmappingrule.md) cmdlet. Specify the `ProductionNetwork`, `IsolatedNetworkName` and `VLANID` parameter values. Save the result to the `$maprule` variable.
4. Run the [`New-VBRViVirtualLabNetworkOptions`](new-vbrvivirtuallabnetworkoptions.md) cmdlet. Specify the `NetworkMappingRule`, `IPAddress`, `SubnetMask` and `MasqueradeIPAddress` parameter values. Save the result to the `$isolated` variable.
5. Run the `Set-VBRViVirtualLabNetworkOptions` cmdlet. Set the `$isolated` variable as the `Options` parameter value. Specify the `SubnetMask` parameter value.

### Example 2. Modifying Prefix Length

This example shows how to modify a prefix length of an isolated network that connects to the to production network.

```
$server = Get-VBRServer -Name "srv01.tech.local"
$network = Get-VBRViServerNetworkInfo -Server $server
$maprule = New-VBRViNetworkMappingRule -ProductionNetwork $network[3] -IsolatedNetworkName "Sandbox01 Private VM Network" -VLANID 5
$isolated = New-VBRViVirtualLabNetworkOptions -NetworkMappingRule $maprule -IPv6Address fdd1:aa80:bb80:cc80:dd80:ee80:fe80:10 -IPv6PrefixLength 64 -MasqueradeIPv6Address fdd1:ab80:bb80:cc88::
Set-VBRViVirtualLabNetworkOptions -Options $isolated -IPv6PrefixLength 64
```

Perform the following steps:

1. Run the [`Get-VBRServer`](get-vbrserver.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$server` variable.
2. Run the [`Get-VBRViServerNetworkInfo`](get-vbrviservernetworkinfo.md) cmdlet. Set the `$server` variable as the `Server` parameter value. Save the result to the `$network` variable.
3. Run the [`New-VBRViNetworkMappingRule`](new-vbrvinetworkmappingrule.md) cmdlet. Specify the `ProductionNetwork`, `IsolatedNetworkName` and `VLANID` parameter values. Save the result to the `$maprule` variable.
4. Run the [`New-VBRViVirtualLabNetworkOptions`](new-vbrvivirtuallabnetworkoptions.md) cmdlet. Specify the `NetworkMappingRule`, `IPv6Address`, `IPv6PrefixLength` and `MasqueradeIPv6Address` parameter values. Save the result to the `$isolated` variable.
5. Run the `Set-VBRViVirtualLabNetworkOptions` cmdlet. Set the `$isolated` variable as the `Options` parameter value. Specify the new `IPv6PrefixLength` parameter value.

### Example 3. Modifying IP of Proxy Appliance

This example shows how to modify an IP address of a proxy appliance to which an isolated network is connected. The isolated network will connect to the proxy appliance that has the `172.17.1.7` IP address.

```
$server = Get-VBRServer -Name "srv01.tech.local"
$network = Get-VBRViServerNetworkInfo -Server $server
$maprule = New-VBRViNetworkMappingRule -ProductionNetwork $network[3] -IsolatedNetworkName "Sandbox01 Private VM Network" -VLANID 5
$isolated = New-VBRViVirtualLabNetworkOptions -NetworkMappingRule $maprule -IPAddress 172.17.1.2 -SubnetMask 255.255.0.0 -MasqueradeIPAddress 172.22.22.22
Set-VBRViVirtualLabNetworkOptions -Options $isolated -IPAddress 172.17.1.7
```

Perform the following steps:

1. Run the [`Get-VBRServer`](get-vbrserver.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$server` variable.
2. Run the [`Get-VBRViServerNetworkInfo`](get-vbrviservernetworkinfo.md) cmdlet. Set the `$server` variable as the `Server` parameter value. Save the result to the `$network` variable.
3. Run the [`New-VBRViNetworkMappingRule`](new-vbrvinetworkmappingrule.md) cmdlet. Specify the `ProductionNetwork`, `IsolatedNetworkName` and `VLANID` parameter values. Save the result to the `$maprule` variable.
4. Run the [`New-VBRViVirtualLabNetworkOptions`](new-vbrvivirtuallabnetworkoptions.md) cmdlet. Specify the `NetworkMappingRule`, `IPAddress`, `SubnetMask` and `MasqueradeIPAddress` parameter values. Save the result to the `$isolated` variable.
5. Run the `Set-VBRViVirtualLabNetworkOptions` cmdlet. Set the `$isolated` variable as the `Options` parameter value. Specify the `IPAddress` parameter value.
