Disconnect networks

To remove a connection between a Google Virtual Private Cloud (VPC) network and a Dedicated Interconnect connection, delete the related VLAN attachment (also known as an interconnectAttachment). After you delete the attachment, no traffic can travel between the VPC network and your on-premises network through the connection. Also, BGP sessions that use the attachment go down.

Billing for the VLAN attachment stops when you delete it; however, you're still billed for the Interconnect connection, even if no traffic is passing through it.
