      • 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.

Complete the following fields and then click Next.

Google On-Ramp and Capacity
Create a NAT-capable connection
Select this option if you want to be able to enable NAT for the connection. This ensures the connection will provision on a device that allows NAT.
This is the Google on-ramp location you would like to use. This cannot be changed after it is provisioned.
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.
Connection Details
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.

VLAN attachment name
Enter the exact VLAN attachment name you provided to Google.
Connection description
Enter a description for the connection.


Select a billing account and then click Place Order.

The connection should provision within a few minutes.

Activate the connection in Google Cloud Console

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

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