Google Dedicated Interconnect Process Overview

For a general overview of using interconnects with PacketFabric, see Google Cloud Interconnect Overview.


1. Create a Google Cloud Platform (GCP) account and set up a Virtual Private Cloud (VPC).

The VPC is the heart of your Google Cloud environment and is the target of your interconnect connection.

2. Configure a Cloud Router for your VPC.

This can be done when you set up your VPC or you can wait and create one when you attach the VLAN.

3. Create a PacketFabric account.

Before you can log in, your account is manually reviewed and then approved by the PacketFabric team. You should receive approval within 24 hours.

4. Provision a port and install a cross connect.

Provisioning a port and generating the LOA only takes a few minutes.

As soon as the port is provisioned, download the LOA and send it to the site provider to install a cross connect between your equipment and PacketFabric. Once this is completed, you will have access to the full PacketFabric network fabric.

At this point, your interconnect will look roughly like this:

Google Dedicated Interconnect to PacketFabric Prereqs

NOTE: Google allows 10 Gbps and 100 Gbps Dedicated Interconnects. You should have enough source port capacity to fully utilize this.

Keep in mind that you can provision multiple services on each port, and connect multiple source ports to interconnects. For some high-level examples, see Google Cloud Interconnects as Part of a Custom Network.

Order the Google Dedicated Interconnect

1. Log in to the Google Cloud Console and create a Dedicated Interconnect.

When ordering the interconnect, the following is important:

  • When selecting a location, you must select one of the PacketFabric on-ramp locations.
  • When selecting a capacity, select either 10 Gbps or 100 Gbps.
  • When you are asked to provide a company name, you must enter “PacketFabric.” This allows us to set up the cross connect between our port and Google.

2. Install the cross connect between Google and PacketFabric in the on-ramp facility.

For this step, all you need to do is forward the LOA that Google sends you to your PacketFabric client success manager.

3. Verify the cross connect.

Google periodically tests light levels to check for the cross connect.

When they confirm that it is installed correctly, they will send you an email containing an IP address with which to configure your on-premises router. Set this aside.

Create the Dedicated PacketFabric Connection

1. Log in to the PacketFabric portal and create a Dedicated Cloud Connection to Google.

Provide the same location and capacity that you selected when creating your Google Dedicated Interconnect.

2. Add an untagged virtual circuit (VC) to the cloud connection.

This first virtual circuit is used for Google's automated testing. LACP is automatically enabled per Google's requirements, but you must leave the destination VLAN untagged.

You can later edit the virtual circuit to tag the destination VLAN, or delete it and build a new one.

3. Configure your on-premises router with the IP address sent to you by Google.

Note the source VLAN ID for your virtual circuit and the test IP address Google sent earlier. Use these to configure your on-premises router.

Google periodically pings the IP address to confirm the connection. When confirmed, you are sent an email notifying you that the interconnect is ready to use.

Build Virtual Connections

1. Add a destination VLAN ID to the test virtual circuit.

You can either delete the test virtual circuit and create a new one, or modify the one you have to include a destination VLAN ID.

2. Add a VLAN attachment in Google Console.

Every PacketFabric virtual circuit must have a corresponding VLAN attachment.

Establish a BGP Session

Configure your on-premises routers.

The last step is to establish a BGP session between your on-premises routers and the Google Cloud Router in your VPC.

NOTE: You must complete all the steps above for every redundant interconnect.
