Description

The Add-AzVirtualNetworkSubnetConfig cmdlet adds a subnet configuration to an existing Azure virtual network.

Examples

Example 1: Add a subnet to an existing virtual network

New-AzResourceGroup -Name TestResourceGroup -Location centralus
    $frontendSubnet = New-AzVirtualNetworkSubnetConfig -Name frontendSubnet -AddressPrefix "10.0.1.0/24"
    $virtualNetwork = New-AzVirtualNetwork -Name MyVirtualNetwork -ResourceGroupName TestResourceGroup -Location centralus -AddressPrefix "10.0.0.0/16" -Subnet $frontendSubnet
    Add-AzVirtualNetworkSubnetConfig -Name backendSubnet -VirtualNetwork $virtualNetwork -AddressPrefix "10.0.2.0/24"
    $virtualNetwork | Set-AzVirtualNetwork

This example first creates a resource group as a container of the resources to be created. It then creates a subnet configuration and uses it to create a virtual network. The Add-AzVirtualNetworkSubnetConfig is then used to add a subnet to the in-memory representation of the virtual network. The Set-AzVirtualNetwork command updates the existing virtual network with the new subnet.

Example 2: Add a delegation to a subnet being added to an existing virtual network

$vnet = Get-AzVirtualNetwork -Name "myVNet" -ResourceGroupName "myResourceGroup"
$delegation = New-AzDelegation -Name "myDelegation" -ServiceName "Microsoft.Sql/servers"
Add-AzVirtualNetworkSubnetConfig -Name "mySubnet" -VirtualNetwork $vnet -AddressPrefix "10.0.2.0/24" -Delegation $delegation | Set-AzVirtualNetwork

This example first gets an existing vnet. Then, it creates a delegation object in memory. Finally, it creates a new subnet with that delegation that is added to the vnet. The modified configuration is then sent to the server.
