Disconnect networks

To remove a connection between a Virtual Private Cloud (VPC) network and a Cross-Cloud 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 remote cloud network. Also, Border Gateway Protocol (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 Cross-Cloud Interconnect connection, even if no traffic is passing through it.
