Lab 05 - Implement Intersite Connectivity

Student lab manual

Lab scenario

Contoso has its datacenters in Boston, New York, and Seattle offices connected via a mesh wide-area network links, with full connectivity between them. You need to implement a lab environment that will reflect the topology of the Contoso's on-premises networks and verify its functionality.

Objectives

In this lab, you will:

  • Task 1: Provision the lab environment
  • Task 2: Configure local and global virtual network peering
  • Task 3: Test intersite connectivity

Task 1: Provision the lab environment

In this task, you will deploy three virtual machines, each into a separate virtual network, with two of them in the same Azure region and the third one in another Azure region.

  1. Sign in to the Azure portal.

  2. In the Azure portal, open the Azure Cloud Shell by clicking on the icon in the top right of the Azure Portal.

  3. If prompted to select either Bash or PowerShell, select PowerShell.

    Note

    : If this is the first time you are starting Cloud Shell and you are presented with the You have no storage mounted message, select the subscription you are using in this lab, and click Create storage.

  4. In the toolbar of the Cloud Shell pane, click the Upload/Download files icon, in the drop-down menu, click Upload and upload the files \Allfiles\Labs\05\az104-05-vnetvm-template.json and \Allfiles\Labs\05\az104-05-vnetvm-parameters.json into the Cloud Shell home directory.

  5. From the Cloud Shell pane, run the following to create the first resource group that will be hosting the first virtual network and the pair of virtual machines (replace the [Azure_region_1] placeholder with the name of an Azure region where you intend to deploy these Azure virtual machines):

    $location = '[Azure_region_1]'

$rgName = 'az104-05-rg0'

New-AzResourceGroup -Name $rgName -Location $location

  6. From the Cloud Shell pane, run the following to create the first virtual network and deploy a virtual machine into it by using the template and parameter files you uploaded:

    New-AzResourceGroupDeployment `
   -ResourceGroupName $rgName `
   -TemplateFile $HOME/az104-05-vnetvm-template.json `
   -TemplateParameterFile $HOME/az104-05-vnetvm-parameters.json `
   -nameSuffix 0 `
   -AsJob

  7. From the Cloud Shell pane, run the following to create the second resource group that will be hosting the second virtual network and the second virtual machine

    $rgName = 'az104-05-rg1'

New-AzResourceGroup -Name $rgName -Location $location

  8. From the Cloud Shell pane, run the following to create the second virtual network and deploy a virtual machine into it by using the template and parameter files you uploaded:

    New-AzResourceGroupDeployment `
   -ResourceGroupName $rgName `
   -TemplateFile $HOME/az104-05-vnetvm-template.json `
   -TemplateParameterFile $HOME/az104-05-vnetvm-parameters.json `
   -nameSuffix 1 `
   -AsJob

  9. From the Cloud Shell pane, run the following to create the third resource group that will be hosting the third virtual network and the third virtual machine (replace the [Azure_region_2] placeholder with the name of another Azure region where you can deploy Azure virtual machines, different from the Azure region you used for the other two deployments):

    $location = '[Azure_region_2]'

$rgName = 'az104-05-rg2'

New-AzResourceGroup -Name $rgName -Location $location

  10. From the Cloud Shell pane, run the following to create the third virtual network and deploy a virtual machine into it by using the template and parameter files you uploaded:

    New-AzResourceGroupDeployment `
   -ResourceGroupName $rgName `
   -TemplateFile $HOME/az104-05-vnetvm-template.json `
   -TemplateParameterFile $HOME/az104-05-vnetvm-parameters.json `
   -nameSuffix 2 `
   -AsJob

    Note

    : Wait for the deployments to complete before proceeding to the next task. This should take about 2 minutes.

    Note

    : To verify the status of the deployments, you can examine the properties of the resource groups you created in this task.

  11. Close the Cloud Shell pane.

Task 2: Configure local and global virtual network peering

In this task, you will configure local and global peering between the virtual networks you deployed in the previous tasks.

  1. In the Azure portal, search for and select Virtual networks.

  2. Review the virtual networks you created in the previous task and verify that the first two are located in the same Azure region and the third one in a different Azure region.

    Note

    : The template you used for deployment of the three virtual networks ensures that the IP address ranges of the three virtual networks do not overlap.

  3. In the list of virtual networks, click az104-05-vnet0.

  4. On the az104-05-vnet0 virtual network blade, in the Settings section, click Peerings and then click + Add.

  5. Add a peering with the following settings (leave others with their default values):

    Setting Value
    Name of the peering from az104-05-vnet0 to remote virtual network az104-05-vnet0_to_az104-05-vnet1
    Virtual network deployment model Resource manager
    Subscription the name of the Azure subscription you are using in this lab
    Virtual network az104-05-vnet1 (az104-05-rg1)
    Name of the peering from az104-05-vnet1 to az104-05-vnet0 az104-05-vnet1_to_az104-05-vnet0
    Allow virtual network access from az104-05-vnet0 to az104-05-vnet1 Enabled
    Allow virtual network access from az104-05-vnet1 to az104-05-vnet0 Enabled
    Allow forwarded traffic from az104-05-vnet1 to az104-05-vnet0 Disabled
    Allow forwarded traffic from az104-05-vnet0 to az104-05-vnet1 Disabled
    Allow gateway transit (Uncheck Box)

    Note

    : This step establishes two local peerings - one from az104-05-vnet0 to az104-05-vnet1 and the other from az104-05-vnet1 to az104-05-vnet0.

  6. On the az104-05-vnet0 virtual network blade, in the Settings section, click Peerings and then click + Add.

  7. Add a peering with the following settings (leave others with their default values):

    Setting Value
    Name of the peering from az104-05-vnet0 to remote virtual network az104-05-vnet0_to_az104-05-vnet2
    Virtual network deployment model Resource manager
    Subscription the name of the Azure subscription you are using in this lab
    Virtual network az104-05-vnet2 (az104-05-rg2)
    Name of the peering from az104-05-vnet2 to az104-05-vnet0 az104-05-vnet2_to_az104-05-vnet0
    Allow virtual network access from az104-05-vnet0 to az104-05-vnet2 Enabled
    Allow virtual network access from az104-05-vnet2 to az104-05-vnet0 Enabled
    Allow forwarded traffic from az104-05-vnet2 to az104-05-vnet0 Disabled
    Allow forwarded traffic from az104-05-vnet0 to az104-05-vnet2 Disabled
    Allow gateway transit (Uncheck Box)

    Note

    : This step establishes two global peerings - one from az104-05-vnet0 to az104-05-vnet2 and the other from az104-05-vnet2 to az104-05-vnet0.

  8. Navigate back to the Virtual networks blade and, in the list of virtual networks, click az104-05-vnet1.

  9. On the az104-05-vnet1 virtual network blade, in the Settings section, click Peerings and then click + Add.

  10. Add a peering with the following settings (leave others with their default values):

    Setting Value
    Name of the peering from az104-05-vnet1 to remote virtual network az104-05-vnet1_to_az104-05-vnet2
    Virtual network deployment model Resource manager
    Subscription the name of the Azure subscription you are using in this lab
    Virtual network az104-05-vnet2 (az104-05-rg2)
    Name of the peering from az104-05-vnet2 to az104-05-vnet1 az104-05-vnet2_to_az104-05-vnet1
    Allow virtual network access from az104-05-vnet1 to az104-05-vnet2 Enabled
    Allow virtual network access from az104-05-vnet2 to az104-05-vnet1 Enabled
    Allow forwarded traffic from az104-05-vnet2 to az104-05-vnet1 Disabled
    Allow forwarded traffic from az104-05-vnet1 to az104-05-vnet2 Disabled
    Allow gateway transit (Uncheck Box)

    Note

    : This step establishes two global peerings - one from az104-05-vnet1 to az104-05-vnet2 and the other from az104-05-vnet2 to az104-05-vnet1.

Task 3: Test intersite connectivity

In this task, you will test connectivity between virtual machines on the three virtual networks that you connected via local and global peering in the previous task.

  1. In the Azure portal, search for and select Virtual machines.

  2. In the list of virtual machines, click az104-05-vm0.

  3. On the az104-05-vm0 blade, click Connect, in the drop-down menu, click RDP, on the Connect with RDP blade, click Download RDP File and follow the prompts to start the Remote Desktop session.

    Note

    : This step refers to connecting via Remote Desktop from a Windows computer. On a Mac, you can use Remote Desktop Client from the Mac App Store and on Linux computers you can use an open source RDP client software.

    Note

    : You can ignore any warning prompts when connecting to the target virtual machines.

  4. When prompted, sign in by using the Student username and Pa55w.rd1234 password.

  5. Within the Remote Desktop session to az104-05-vm0, right-click the Start button and, in the right-click menu, click Windows PowerShell (Admin).

  6. In the Windows PowerShell console window, run the following to test connectivity to az104-05-vm1 (which has the private IP address of 10.51.0.4) over TCP port 3389:

    Test-NetConnection -ComputerName 10.51.0.4 -Port 3389 -InformationLevel 'Detailed'

    Note

    : The test uses TCP 3389 since this is this port is allowed by default by operating system firewall.

  7. Examine the output of the command and verify that the connection was successful.

  8. In the Windows PowerShell console window, run the following to test connectivity to az104-05-vm2 (which has the private IP address of 10.52.0.4):

    Test-NetConnection -ComputerName 10.52.0.4 -Port 3389 -InformationLevel 'Detailed'

  9. Switch back to the Azure portal on your lab computer and navigate back to the Virtual machines blade.

  10. In the list of virtual machines, click az104-05-vm1.

  11. On the az104-05-vm1 blade, click Connect, in the drop-down menu, click RDP, on the Connect with RDP blade, click Download RDP File and follow the prompts to start the Remote Desktop session.

    Note

    : This step refers to connecting via Remote Desktop from a Windows computer. On a Mac, you can use Remote Desktop Client from the Mac App Store and on Linux computers you can use an open source RDP client software.

    Note

    : You can ignore any warning prompts when connecting to the target virtual machines.

  12. When prompted, sign in by using the Student username and Pa55w.rd1234 password.

  13. Within the Remote Desktop session to az104-05-vm1, right-click the Start button and, in the right-click menu, click Windows PowerShell (Admin).

  14. In the Windows PowerShell console window, run the following to test connectivity to az104-05-vm2 (which has the private IP address of 10.52.0.4) over TCP port 3389:

    Test-NetConnection -ComputerName 10.52.0.4 -Port 3389 -InformationLevel 'Detailed'

    Note

    : The test uses TCP 3389 since this is this port is allowed by default by operating system firewall.

  15. Examine the output of the command and verify that the connection was successful.

Clean up resources

Note

: Remember to remove any newly created Azure resources that you no longer use. Removing unused resources ensures you will not see unexpected charges.

  1. In the Azure portal, open the PowerShell session within the Cloud Shell pane.

  2. List all resource groups created throughout the labs of this module by running the following command:

    Get-AzResourceGroup -Name 'az104-05*'

  3. Delete all resource groups you created throughout the labs of this module by running the following command:

    Get-AzResourceGroup -Name 'az104-05*' | Remove-AzResourceGroup -Force -AsJob

    Note

    : The command executes asynchronously (as determined by the -AsJob parameter), so while you will be able to run another PowerShell command immediately afterwards within the same PowerShell session, it will take a few minutes before the resource groups are actually removed.
