To remove a connection between a Google Virtual Private Cloud (VPC) network and a
Dedicated Interconnect connection, you 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, and 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 Dedicated Interconnect connection, even if no
traffic is passing through it.
