This page describes the steps to successfully create and provision a Partner Interconnect connection with a service provider.
Before you start the Partner Interconnect provisioning process, you must already have connectivity with a supported service provider.
To create and provision a Partner Interconnect connection, follow these steps:
Create a VLAN attachment for a Partner Interconnect connection. This step generates a pairing key that you share with your service provider. The pairing key is a unique key that lets a service provider identify and connect to your Virtual Private Cloud (VPC) network and associated Cloud Router. The service provider requires this key to complete the configuration of your VLAN attachment.
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. After their configuration is complete, you receive an email notification from Google.
After the service provider configures your connection, you must activate it. Activating the connection and checking its activation status enables you to verify that you established connectivity with the expected service provider.
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 IP address from the 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.
