Peer two virtual networks

This script creates and connects two virtual networks in the same region through the Azure network. After running the script, you will create a peering between two virtual networks.

If needed, install the Azure PowerShell using the instruction found in the Azure PowerShell guide, and then run Connect-AzAccount to create a connection with Azure.

If you don't have an Azure subscription, create an Azure free account before you begin.

Sample script

Note

We recommend that you use the Azure Az PowerShell module to interact with Azure. See Install Azure PowerShell to get started. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.

# Variables for common values
$rgName='MyResourceGroup'
$location='eastus'

# Create a resource group.
New-AzResourceGroup -Name $rgName -Location $location

# Create virtual network 1.
$vnet1 = New-AzVirtualNetwork -ResourceGroupName $rgName -Name 'Vnet1' -AddressPrefix '10.0.0.0/16' -Location $location

# Create virtual network 2.
$vnet2 = New-AzVirtualNetwork -ResourceGroupName $rgName -Name 'Vnet2' -AddressPrefix '10.1.0.0/16' -Location $location

# Peer VNet1 to VNet2.
Add-AzVirtualNetworkPeering -Name 'LinkVnet1ToVnet2' -VirtualNetwork $vnet1 -RemoteVirtualNetworkId $vnet2.Id

# Peer VNet2 to VNet1.
Add-AzVirtualNetworkPeering -Name 'LinkVnet2ToVnet1' -VirtualNetwork $vnet2 -RemoteVirtualNetworkId $vnet1.Id
