This article helps you connect your virtual network to your virtual hub using PowerShell. 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.
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.
- Verify that you have an Azure subscription. If you don't already have an Azure subscription, you can activate your MSDN subscriber benefits or sign up for a trial subscription.
- The following steps assume that you have already created a site-to-site Virtual WAN VPN gateway.
You can 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.
Open the PowerShell console with elevated privileges and connect to your Azure account. The Connect-AzAccount -Environment AzureChinaCloud 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".
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"Create a connection to peer the virtual network to the virtual hub.
New-AzVirtualHubVnetConnection -ResourceGroupName "TestRG" -VirtualHubName "Hub1" -Name "VNet1-connection" -RemoteVirtualNetwork $remoteVirtualNetwork
