Create a Google Partner Interconnect Connection


  • An existing VPC created through your Google Cloud account. For more information, see Google Cloud - Using VPC networks.
  • An existing PacketFabric interface that connects your on-premises network to PacketFabric. For more information, see Create a Port.

Create a VLAN attachment in Google Cloud Console

  1. Click the menu in the upper right to open the product list.


  2. Scroll down to Networking and select Hybrid Connectivity > Interconnect.


  3. If you already have previous VLAN attachments, click Add VLAN Attachment. Otherwise, click Get Started.


  4. Select Partner Interconnect and then click Continue.


  5. Click I already have a service provider.

  6. Complete the following fields:

    • Header row

      • Field
      • Description
    • r1

      • Redundancy
      • Select whether you are creating a single attachment, redundant attachments, or adding a redundant attachment.
    • r1

    • r1

      • Region

      • Select the region in which you want to connect. PacketFabric on-ramps can serve all of Google’s U.S. regions and northamerica-northeast-1 (Montreal).

        Internationally, all of Google’s European regions are accessible from our London on-ramp.

        Our Sydney on-ramp serves Google’s australia-southeast-1 regions.

    • r1

      • Cloud Router

      • Note - This refers to Google’s Cloud Router product, which is not related to the PacketFabric Cloud Router.

        If you have already configured a Cloud Router for the selected region, you can select it. If you are creating redundant VLAN attachments, each attachment requires its own Cloud Router.

        Otherwise, create a new cloud router.

        IMPORTANT: You must select or create a Cloud Router with its Google ASN set to 16550. This is a Google requirement for all Partner Interconnects.
    • r1

      • VLAN attachment name
      • Enter a name for this VLAN attachment.
    • r1

      • Description
      • Optionally, enter a description for this VLAN attachment.
    • r1

      • Maximum transmission unit (MTU)
      • Select an MTU for the VLAN attachment. PacketFabric supports up to 9000 bytes MTU.
  7. Click Create.

  8. Copy the pairing key. You need this when creating your hosted connection from the PacketFabric portal.

  9. Leave the Enable option unselected.

  10. Click OK.

Create a Hosted Cloud Connection in the PacketFabric portal

  1. Log in to the PacketFabric portal. From the dashboard, click Hosted Cloud under Create New Service:


  2. Select Google Cloud.

Complete the following fields:

Pairing Key

Enter your GCP pairing key. This is generated when you create a VLAN attachment.

IMPORTANT: Ensure your pairing key ends with /1 or /2. You’ll get a provisioning error if it ends with /any.

The trailing /1 and /2 indicate which interconnect path your PacketFabric circuit should follow. The primary VLAN attachment ends in /1 and the redundant attachment ends in /2.

Select From

Select the source interface. The source interface is the PacketFabric interface directly connected to your network.

You must have at least one interface before continuing. If there is nothing to select, you need to create a new port.

Select Destination Region & Speed
Select Destination Region
This is the Google on-ramp location you would like to use. This cannot be changed after it is provisioned.
Select Speed
This is the speed/capacity you are setting for your VLAN attachment.
NOTE: The capacity you select determines the hourly price Google charges you for your VLAN attachment. See Google’s Partner Interconnect Pricing for more information.
Product Confirmation
Product Description
Enter a description for the connection.
Select the appropriate billing account to associate with this service.
  • Source VLAN ID: This is the VLAN ID that faces your source interface (your on-premises network). You can manually enter the ID or click Next Available. If you click Next Available, we find the highest in-use VLAN ID and increment by one. For example, if the highest in-use ID is 15, this field autopopulates with 16.
  • VLAN Attachment Name: Enter the exact VLAN attachment name you provided to Google.

Review your information. When everything is correct, click Place Order.

The connection might take a few minutes to provision.

Redundant VLAN attachments

Redundant VLAN attachments are optional. However, Google’s SLA does not cover VLAN attachments unless they are part of a redundant pair.

Every redundant VLAN attachment must have a corresponding PacketFabric Hosted Cloud Connection.

Each VLAN attachment has a unique pairing key.

IMPORTANT: A VLAN attachment is not considered redundant unless it is specifically created as a “redundant” attachment through Google.

In the Google Cloud Console, this means selecting Add a redundant VLAN to an existing VLAN or Create a redundant pair of VLAN attachments.

Redundant attachments can be identified by the trailing /2 in their pairing key.

Activate your attachment

  1. Once provisioning is complete, return to the Google Cloud Console.

  2. Refresh the page. Note that the VLAN attachment status is now Activation needed.


  3. Click Activate.

  4. Click Accept.

  5. Under Connection, click Configure BGP.


  6. Enter your ASN into the field provided and click Save and continue.

  7. From the VLAN attachment page, click Activate.


Next steps (all users)

Configure your routers as needed. For more information, see Configuring on-premises router settings.

NOTE: Ensure that multi-hop BGP is enabled on your on-premises router with 2+ hops. Google recommends at least 4. For more information, see Partner Interconnect Troubleshooting - Google.

Next steps (marketplace-to-cloud users)

Your connection remains disconnected until the other party accepts your request. Billing does not begin until the other party accepts and your circuit is provisioned.

You can cancel the request or view status under Network > Connection Requests. Click Sent Requests.
