Connect a virtual network to a Virtual WAN hub - PowerShell

  • Grein

This article helps you connect your virtual network to your virtual hub using PowerShell. You can also use Azure portal to complete this task. Repeat these steps for each VNet that you want to connect.

Before you create a connection, be aware of the following:

  • A virtual network can only be connected to one virtual hub at a time.

  • In order to connect it to a virtual hub, the remote virtual network can't have a gateway (ExpressRoute or VPN) or RouteServer.

  • Some configuration settings, such as Propagate static route, can only be configured in the Azure portal at this time. See the Azure portal version of this article for steps.

Important

If VPN gateways are present in the virtual hub, this operation as well as any other write operation on the connected VNet can cause disconnection to point-to-site clients as well as reconnection of site-to-site tunnels and BGP sessions.

Prerequisites

Azure PowerShell

This article uses PowerShell cmdlets. To run the cmdlets, you can use Azure Cloud Shell. Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

To open Cloud Shell, just select Open Cloudshell from the upper-right corner of a code block. You can also open Cloud Shell on a separate browser tab by going to https://shell.azure.com/powershell. Select Copy to copy the blocks of code, paste them into Cloud Shell, and select the Enter key to run them.

You can also install and run the Azure PowerShell cmdlets locally on your computer. PowerShell cmdlets are updated frequently. If you haven't installed the latest version, the values specified in the instructions may fail. To find the versions of Azure PowerShell installed on your computer, use the Get-Module -ListAvailable Az cmdlet. To install or update, see Install the Azure PowerShell module.

Sign in

If you're using Azure Cloud Shell you'll automatically be directed to sign into your account after you open Cloudshell. You don't need to run Connect-AzAccount. Once signed in, you can still change subscriptions if necessary by using Get-AzSubscription and Select-AzSubscription.

If you're running PowerShell locally, open the PowerShell console with elevated privileges and connect to your Azure account. The Connect-AzAccount cmdlet prompts you for credentials. After you authenticate, it downloads your account settings so that they're available to Azure PowerShell. You can change subscription by using Get-AzSubscription and Select-AzSubscription -SubscriptionName "Name of subscription".

Add a connection

  1. Declare the variables for the existing resources, including the existing virtual network.

    $resourceGroup = Get-AzResourceGroup -ResourceGroupName "TestRG" 
$virtualWan = Get-AzVirtualWan -ResourceGroupName "TestRG" -Name "TestVWAN1"
$virtualHub = Get-AzVirtualHub -ResourceGroupName "TestRG" -Name "Hub1"
$remoteVirtualNetwork = Get-AzVirtualNetwork -Name "VNet1" -ResourceGroupName "TestRG"

  2. Create a connection to peer the virtual network to the virtual hub.

    New-AzVirtualHubVnetConnection -ResourceGroupName "TestRG" -VirtualHubName "Hub1" -Name "VNet1-connection" -RemoteVirtualNetwork $remoteVirtualNetwork
