Create a virtual network peering - Resource Manager, different subscriptions and Microsoft Entra tenants

Raksts
07/01/2024

In this tutorial, you learn to create a virtual network peering between virtual networks created through Resource Manager. The virtual networks exist in different subscriptions that might belong to different Microsoft Entra tenants. Peering two virtual networks enables resources in different virtual networks to communicate with each other with the same bandwidth and latency as though the resources were in the same virtual network. Learn more about Virtual network peering.

Depending on whether, the virtual networks are in the same, or different subscriptions the steps to create a virtual network peering are different. Steps to peer networks created with the classic deployment model are different. For more information about deployment models, see Azure deployment model.

Learn how to create a virtual network peering in other scenarios by selecting the scenario from the following table:

Azure deployment model	Azure subscription
Both Resource Manager	Same
One Resource Manager, one classic	Same
One Resource Manager, one classic	Different

A virtual network peering can't be created between two virtual networks deployed through the classic deployment model. If you need to connect virtual networks that were both created through the classic deployment model, you can use an Azure VPN Gateway to connect the virtual networks.

This tutorial peers virtual networks in the same region. You can also peer virtual networks in different supported regions. Familiarize yourself with the peering requirements and constraints before peering virtual networks.

Prerequisites

An Azure account or accounts with two active subscriptions. Create an account for free.
An Azure account with permissions in both subscriptions or an account in each subscription with the proper permissions to create a virtual network peering. For a list of permissions, see Virtual network peering permissions.
- To separate the duty of managing the network belonging to each tenant, add the user from each tenant as a guest in the opposite tenant and assign them the Network Contributor role to the virtual network. This procedure applies if the virtual networks are in different subscriptions and Active Directory tenants.
- To establish a network peering when you don't intend to separate the duty of managing the network belonging to each tenant, add the user from tenant A as a guest in the opposite tenant. Then, assign them the Network Contributor role to initiate and connect the network peering from each subscription. With these permissions, the user is able to establish the network peering from each subscription.
- For more information about guest users, see Add Microsoft Entra B2B collaboration users in the Azure portal.
- Each user must accept the guest user invitation from the opposite Microsoft Entra tenant.
Sign-in to the Azure portal.

Azure PowerShell installed locally or Azure Cloud Shell.
Sign in to Azure PowerShell and select the subscription with which you want to use this feature. For more information, see Sign in with Azure PowerShell.
Ensure your Az.Network module is 4.3.0 or later. To verify the installed module, use the command Get-InstalledModule -Name "Az.Network". If the module requires an update, use the command Update-Module -Name Az.Network if necessary.

If you choose to install and use PowerShell locally, this article requires the Azure PowerShell module version 5.4.1 or later. Run Get-Module -ListAvailable Az to find the installed version. If you need to upgrade, see Install Azure PowerShell module. If you're running PowerShell locally, you also need to run Connect-AzAccount to create a connection with Azure.

In the following steps, learn how to peer virtual networks in different subscriptions and Microsoft Entra tenants.

You can use the same account that has permissions in both subscriptions or you can use separate accounts for each subscription to set up the peering. An account with permissions in both subscriptions can complete all of the steps without signing out and signing in to portal and assigning permissions.

The following resources and account examples are used in the steps in this article:

User account	Resource group	Subscription	Virtual network
user-1	test-rg	subscription-1	vnet-1
user-2	test-rg-2	subscription-2	vnet-2

Create virtual network - vnet-1

Note

If you are using a single account to complete the steps, you can skip the steps for logging out of the portal and assigning another user permissions to the virtual networks.

The following procedure creates a virtual network with a resource subnet.

In the portal, search for and select Virtual networks.
On the Virtual networks page, select + Create.

On the Basics tab of Create virtual network, enter or select the following information:

Setting	Value
Project details
Subscription	Select your subscription.
Resource group	Select Create new. Enter test-rg in Name. Select OK.
Instance details
Name	Enter vnet-1.
Region	Select East US 2.

Select Next to proceed to the Security tab.
Select Next to proceed to the IP Addresses tab.
In the address space box in Subnets, select the default subnet.
In Edit subnet, enter or select the following information:

Setting Value

Subnet purpose Leave the default Default.

Name Enter subnet-1.
Leave the rest of the settings as their defaults. Select Save.
Select Save.
Select Review + create at the bottom of the screen, and when validation passes, select Create.

Setting	Value
Subnet purpose	Leave the default Default.
Name	Enter subnet-1.

Use Connect-AzAccount to sign in to subscription-1.

Connect-AzAccount

If you're using one account for both subscriptions, sign in to that account and change the subscription context to subscription-1 with Set-AzContext.

Set-AzContext -Subscription subscription-1

Create a resource group - test-rg

An Azure resource group is a logical container where Azure resources are deployed and managed.

Create a resource group with New-AzResourceGroup:

$rsg = @{
    Name = 'test-rg'
    Location = 'eastus2'
}
New-AzResourceGroup @rsg

Create the virtual network

Create a virtual network with New-AzVirtualNetwork. This example creates a subnet-1 virtual network named vnet-1 in the West US 3 location:

$vnet = @{
    Name = 'vnet-1'
    ResourceGroupName = 'test-rg'
    Location = 'eastus2'
    AddressPrefix = '10.0.0.0/16'
}
$virtualNetwork = New-AzVirtualNetwork @vnet

Add a subnet

Azure deploys resources to a subnet within a virtual network, so you need to create a subnet. Create a subnet configuration named subnet-1 with Add-AzVirtualNetworkSubnetConfig:

$subnet = @{
    Name = 'subnet-1'
    VirtualNetwork = $virtualNetwork
    AddressPrefix = '10.0.0.0/24'
}
$subnetConfig = Add-AzVirtualNetworkSubnetConfig @subnet

Associate the subnet to the virtual network

You can write the subnet configuration to the virtual network with Set-AzVirtualNetwork. This command creates the subnet:

$virtualNetwork | Set-AzVirtualNetwork

Use az sign-in to sign in to subscription-1.

az login

If you're using one account for both subscriptions, sign in to that account and change the subscription context to subscription-1 with az account set.

az account set --subscription "subscription-1"

Create a resource group - test-rg

An Azure resource group is a logical container where Azure resources are deployed and managed.

Create a resource group with az group create:

az group create \
    --name test-rg \
    --location eastus2

Create the virtual network

Create a virtual network and subnet with az network vnet create. This example creates a subnet-1 virtual network named vnet-1 in the West US 3 location.

az network vnet create \
    --resource-group test-rg\
    --location eastus2 \
    --name vnet-1 \
    --address-prefixes 10.0.0.0/16 \
    --subnet-name subnet-1 \
    --subnet-prefixes 10.0.0.0/24

Assign permissions for user-2

A user account in the other subscription that you want to peer with must be added to the network you previously created. If you're using a single account for both subscriptions, you can skip this section.

Remain signed in to the portal as user-1.
In the search box a the top of the portal, enter Virtual network. Select Virtual networks in the search results.
Select vnet-1.
Select Access control (IAM).
Select + Add -> Add role assignment.
In Add role assignment in the Role tab, select Network Contributor.
Select Next.
In the Members tab, select + Select members.
In Select members in the search box, enter user-2.
Select Select.
Select Review + assign.
Select Review + assign.

Use Get-AzVirtualNetwork to obtain the resource ID for vnet-1. Assign user-2 from subscription-2 to vnet-1 with New-AzRoleAssignment.

Use Get-AzADUser to obtain the object ID for user-2.

user-2 is used in this example for the user account. Replace this value with the display name for the user from subscription-2 that you wish to assign permissions to vnet-1. You can skip this step if you're using the same account for both subscriptions.

$id = @{
    Name = 'vnet-1'
    ResourceGroupName = 'test-rg'
}
$vnet = Get-AzVirtualNetwork @id

$obj = Get-AzADUser -DisplayName 'user-2'

$role = @{
    ObjectId = $obj.id
    RoleDefinitionName = 'Network Contributor'
    Scope = $vnet.id
}
New-AzRoleAssignment @role

Use az network vnet show to obtain the resource ID for vnet-1. Assign user-2 from subscription-2 to vnet-1 with az role assignment create.

Use az ad user list to obtain the object ID for user-2.

az ad user list --display-name user-2

[
  {
    "businessPhones": [],
    "displayName": "user-2",
    "givenName": null,
    "id": "16d51293-ec4b-43b1-b54b-3422c108321a",
    "jobTitle": null,
    "mail": "user-2@fabrikam.com",
    "mobilePhone": null,
    "officeLocation": null,
    "preferredLanguage": null,
    "surname": null,
    "userPrincipalName": "user-2_fabrikam.com#EXT#@contoso.onmicrosoft.com"
  }
]

Make note of the object ID of user-2 in field id. In this example, its 16d51293-ec4b-43b1-b54b-3422c108321a.

vnetid=$(az network vnet show \
    --name vnet-1 \
    --resource-group test-rg \
    --query id \
    --output tsv)

az role assignment create \
      --assignee 16d51293-ec4b-43b1-b54b-3422c108321a \
      --role "Network Contributor" \
      --scope $vnetid

Replace the example guid in --assignee with the real object ID for user-2.

    Name = 'vnet-2'
    ResourceGroupName = 'test-rg-2'
    Location = 'eastus2'
    AddressPrefix = '10.1.0.0/16'
}
$virtualNetwork = New-AzVirtualNetwork @vnet

Add a subnet

Azure deploys resources to a subnet within a virtual network, so you need to create a subnet. Create a subnet configuration named subnet-1 with Add-AzVirtualNetworkSubnetConfig:

$subnet = @{
    Name = 'subnet-1'
    VirtualNetwork = $virtualNetwork
    AddressPrefix = '10.1.0.0/24'

    --output table

The peering is successfully established after you see Connected in the Peering status column for both virtual networks in the peering. Any Azure resources you create in either virtual network are now able to communicate with each other through their IP addresses. If you're using Azure name resolution for the virtual networks, the resources in the virtual networks aren't able to resolve names across the virtual networks. If you want to resolve names across virtual networks in a peering, you must create your own DNS (Domain Name System) server or use Azure DNS.

Important

If you update the address space in one of the members of the peer, you must resync the connection to reflect the address space changes. For more information, see Update the address space for a peered virtual network using the Azure portal

For more information about using your own DNS for name resolution, see, Name resolution using your own DNS server.
