Description

The New-AzureRmVirtualNetworkSubnetConfig cmdlet creates a virtual network subnet configuration.

Examples

1: Create a virtual network with two subnets and a network security group

New-AzureRmResourceGroup -Name TestResourceGroup -Location centralus

$rdpRule = New-AzureRmNetworkSecurityRuleConfig -Name rdp-rule -Description "Allow RDP" `
   -Access Allow -Protocol Tcp -Direction Inbound -Priority 100 `
   -SourceAddressPrefix Internet -SourcePortRange * `
   -DestinationAddressPrefix * -DestinationPortRange 3389 
    
$networkSecurityGroup = New-AzureRmNetworkSecurityGroup -ResourceGroupName TestResourceGroup `
  -Location centralus -Name "NSG-FrontEnd" -SecurityRules $rdpRule

$frontendSubnet = New-AzureRmVirtualNetworkSubnetConfig -Name frontendSubnet `
    -AddressPrefix "10.0.1.0/24" -NetworkSecurityGroup $networkSecurityGroup

$backendSubnet = New-AzureRmVirtualNetworkSubnetConfig -Name backendSubnet `
    -AddressPrefix "10.0.2.0/24" -NetworkSecurityGroup $networkSecurityGroup

New-AzureRmVirtualNetwork -Name MyVirtualNetwork -ResourceGroupName TestResourceGroup `
    -Location centralus -AddressPrefix "10.0.0.0/16" -Subnet $frontendSubnet,$backendSubnet

This example creates two new subnet configurations using the New-AzureRmVirtualSubnetConfig cmdlet, and then uses them to create a virtual network. The New-AzureRmVirtualSubnetConfig template only creates an in-memory representation of the subnet. In this example, the frontendSubnet has CIDR 10.0.1.0/24 and references a network security group that allows RDP access. The backendSubnet has CIDR 10.0.2.0/24 and references the same network security group.
