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.
