To disconnect your Virtual Private Cloud (VPC) network and on-premises network,
you must delete the VLAN attachment for the Partner Interconnect
connection. Work with your service provider to initiate the deletion. That way
billing by Google and your service provider stops at the same time.
If you delete the VLAN attachment in Google Cloud first, the attachment is
deleted and Google stops billing you for it. However, your service provider
might not be aware of this change and might continue to charge you for the
connection. Contact your service provider to ensure that they delete your
connection and stop billing you.
After your service provider disconnects your VLAN attachment, the state of your
attachment changes to DEFUNCT, and you can delete the attachment. Both Google
and your service provider stop billing you.
Console
In the Google Cloud console, go to the Cloud Interconnect VLAN
attachments tab.
Select the VLAN attachment to delete. If your service provider
disconnected your attachment, its status is Defunct. If it's in
any other state, you can still delete the attachment, but contact your
service provider to make sure they're aware of this change.
On the VLAN attachment details page, click Delete.
Click Delete to confirm.
gcloud
Describe the VLAN attachment to check whether your service provider
disconnected it; if they did, the state of the attachment is DEFUNCT.
If the state of the attachment is in any other state, you can still
delete the attachment, but contact your service provider to make sure
they're aware of this change.
