This is second part of the earlier written article Create a Azure Virtual Network with Subnet using PowerShell. Here in this blog I will create subnet in already created Azure vNET (Virtual Network). I have defined Azure vNET and subnets in Powershell variables. I am creating a Azure vNET without any subnet as shown in below example.
Download this script New-AzSubnetInvNet.ps1 here or it is also available github.com/janviudapi.
$vNetName = 'global_vnet_eastus' $resourceGroupName = 'vcloud-lab.com' $location = 'eastus' $AddressPrefix = @('10.10.0.0/16') $subnet01Name = 'prod02-10.10.1.x' $subnet01AddressPrefix = '10.10.1.0/24' pwsh | 20:33:02 #Create new Azure Virtual Network without subnet New-AzVirtualNetwork -Name $vNetName -ResourceGroupName $resourceGroupName -Location $location -AddressPrefix $AddressPrefix Name : global_vnet_eastus ResourceGroupName : vcloud-lab.com Location : eastus Id : /subscriptions/9e2xxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/vcloud-lab.com/providers/Microsoft.Network/virtualNetworks/global_vnet_eastus Etag : W/"771556f5-a9ba-4ff4-8fcc-025e2685c813" ResourceGuid : 65c12e07-56bb-4b6d-9316-fcf5d6c0604b ProvisioningState : Succeeded Tags : AddressSpace : { "AddressPrefixes": [ "10.10.0.0/16" ] } DhcpOptions : {} Subnets : [] VirtualNetworkPeerings : [] EnableDdosProtection : false DdosProtectionPlan : null

I have vNET created now without any subnet, I will get the existing vNET information and while creating/adding a new subnet use the vNET information in the parameter. There are few warning while setting subnet configuration, it can be ignored. By using subnet config command it creates subnet config in memory, Changes are not pushed into vNet yet.

This is final command to set subnet configuration to Virtual Network.
