Steps to setup Hybrid Cloud with GNS3

Head to my blog article on this topic to get the full writeup on this tutorial

  1. Install Azure PowerShell module. Instructions

    Install-Module -Name Az -AllowClobber -Scope CurrentUser
  2. Connect to Azure Account (the integration with windows is nice):

  3. Define common network parameters

    # Virtual network
    $RG1         = "TestRG1"
    $VNet1       = "VNet1"
    $Location1   = "East US"
    $VNet1Prefix = ""
    $VNet1ASN    = 65001
    $GW1         = "VNet1GW"
    $FESubnet1   = "FrontEnd"
    $BESubnet1   = "Backend"
    $GwSubnet1   = "GatewaySubnet"
    $FEPrefix1   = ""
    $BEPrefix1   = ""
    $GwPrefix1   = ""
    $GwIP1       = "VNet1GWIP"
    $GwIPConf1   = "gwipconf1"
    # On-premises network - LNGIP1 is the VPN device public IP address
    $LNG1        = "VPNsite1"
    $LNGprefix1  = ""
    $LNGprefix2  = ""
    $LNGIP1      = ""
    # On-premises BGP properties
    $LNGASN1     = 65000
    $BGPPeerIP1  = ""
    # Connection
    $Connection1 = "VNet1ToSite1"
  4. Create a resource group

    New-AzResourceGroup -ResourceGroupName $RG1 -Location $Location1
  5. Create a virtual network

    $fesub1 = New-AzVirtualNetworkSubnetConfig -Name $FESubnet1 -AddressPrefix $FEPrefix1
    $besub1 = New-AzVirtualNetworkSubnetConfig -Name $BESubnet1 -AddressPrefix $BEPrefix1
    $gwsub1 = New-AzVirtualNetworkSubnetConfig -Name $GWSubnet1 -AddressPrefix $GwPrefix1
    $vnet   = New-AzVirtualNetwork `
                -Name $VNet1 `
                -ResourceGroupName $RG1 `
                -Location $Location1 `
                -AddressPrefix $VNet1Prefix `
                -Subnet $fesub1,$besub1,$gwsub1
  6. Request a public IP address for the VPN gateway (this will be a dynamic IP)

    $gwpip    = New-AzPublicIpAddress -Name $GwIP1 -ResourceGroupName $RG1 `
                -Location $Location1 -AllocationMethod Dynamic
    $subnet   = Get-AzVirtualNetworkSubnetConfig -Name 'GatewaySubnet' `
                -VirtualNetwork $vnet
    $gwipconf = New-AzVirtualNetworkGatewayIpConfig -Name $GwIPConf1 `
                -Subnet $subnet -PublicIpAddress $gwpip
  7. Create a VPN gateway (this will take up to 45 minutes)

    New-AzVirtualNetworkGateway -Name $Gw1 -ResourceGroupName $RG1 `
    -Location $Location1 -IpConfigurations $gwipconf -GatewayType Vpn `
    -VpnType RouteBased -GatewaySku VpnGw1 -EnableBgp $True -Asn $VNet1ASN
  8. Create a local network gateway

    New-AzLocalNetworkGateway -Name $LNG1 -ResourceGroupName $RG1 `
    -Location 'East US' -GatewayIpAddress $LNGIP1 `
    -AddressPrefix $LNGprefix1,$LNGprefix2 -Asn $LNGASN1 `
    -BgpPeeringAddress $BGPPeerIP1
  9. Create a S2S VPN connection with BGP Enabled

    $vng1 = Get-AzVirtualNetworkGateway -Name $GW1  -ResourceGroupName $RG1
    $lng1 = Get-AzLocalNetworkGateway   -Name $LNG1 -ResourceGroupName $RG1
    New-AzVirtualNetworkGatewayConnection -Name $Connection1 `
    -ResourceGroupName $RG1 -Location $Location1 `
    -VirtualNetworkGateway1 $vng1 -LocalNetworkGateway2 $lng1 `
    -ConnectionType IPsec -SharedKey "Azure@!b2C3" -EnableBGP $True
  10. Download Premise equipment sample configs. Go to here. or run the following Powershell snippet:

    $RG          = "TestRG1"
    $GWName      = "VNet1GW"
    $Connection  = "VNet1toSite1"
    Get-AzVirtualNetworkGatewayConnectionVpnDeviceConfigScript `
    -Name $Connection -ResourceGroupName $RG -DeviceVendor Cisco `
    -DeviceFamily "Cisco-ISR(IOS)" -FirmwareVersion "Cisco-ISR-15.x--IKEv2+BGP"

Verification and Troubleshooting commands for the CLI

  • Verify the status of the VPN connection

    Get-AzVirtualNetworkGatewayConnection -Name VNet1toSite1 -ResourceGroupName TestRG1
  • Get the BGP peer status

    Get-AzureRmVirtualNetworkGatewayBGPPeerStatus -VirtualNetworkGatewayName VNet1GW -ResourceGroupName TestRG1
  • View the gateway public IP address

    $myGwIp = Get-AzPublicIpAddress -Name $GwIP1 -ResourceGroup $RG1
  • Resize a gateway

    $gateway = Get-AzVirtualNetworkGateway -Name $Gw1 -ResourceGroup $RG1
    Resize-AzVirtualNetworkGateway -GatewaySku VpnGw2 -VirtualNetworkGateway $gateway
  • Reset a gateway (for troubleshooting)

    $gateway = Get-AzVirtualNetworkGateway -Name $Gw1 -ResourceGroup $RG1
    Reset-AzVirtualNetworkGateway -VirtualNetworkGateway $gateway

Removal and Clean-Up

  • Delete a Site-to-Site VPN connection

    Remove-AzVirtualNetworkGatewayConnection -Name $Connection1 -ResourceGroupName $RG1
    Remove-AzVirtualNetworkGatewayConnection -Name $LNG1 -ResourceGroupName $RG1
  • Clean up resources (this deletes everything)

    Remove-AzResourceGroup -Name $RG1
You can’t perform that action at this time.
