Provisioning Overview

When you create a Partner Interconnect connection, you must take the following steps to successfully provision a connection with a service provider:

1. Create a VLAN attachment
Create a VLAN attachment for a Partner Interconnect. This step generates a pairing key that you'll share with your service provider. The pairing key is a unique key that allows a service provider to identify and connect to your VPC network and associated Cloud Router. The service provider requires this key to complete the configuration of your VLAN attachment.
2. Request a connection from your service provider
Go to your service provider to submit the pairing key and other connection details, such as the connection capacity and location. Wait until your service provider configures your connection. They must check that they can serve your requested capacity. You'll receive an email notification from Google after their configuration is complete.
3. Activate your connection
After the service provider configures your connection, you must activate it. Activating the connection, then checking its activation status, enables you to verify that you've established connectivity with the expected service provider.
4. Configure BGP

For layer 2 connections, you must establish a BGP session between your VPC network's Cloud Router and your on-premises router. Use your service provider's console to find the VLAN ID of the connection. Use that VLAN ID and the BGP peer address from Google Cloud Console to configure your on-premises router.

For layer 3 connections, the service provider establishes a BGP session with your VPC network's Cloud Router. This configuration is automated and doesn't require any action from you.
