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 because 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.
