Cross-Cloud Interconnect lets you establish a dedicated physical connection
between Google Cloud and Oracle Cloud Infrastructure (OCI) networks.
Google provisions this physical connection on your behalf. However, as part of the setup
process, you must complete several tasks. You complete some tasks before Google provisions your
connection and some tasks afterward.
Identify locations for your primary and redundant Cross-Cloud Interconnect and
OCI ports. Make a note of the location names. You need these details to
complete the ordering and configuration processes.
Place an order for two
Cross-Cloud Interconnect connections—a primary connection and a redundant
one. In response, Google reserves two ports for you in the facility that you specify. For each
port, we send you a confirmation email that contains instructions related to the next step:
ordering your OCI ports.
Order your OCI ports, and download the
corresponding letter of authorization (LOA). This document confirms your right to use the ports.
Send the LOA to Google, following the instructions from the confirmation email that Google sent
you. After Google receives the LOA, we begin the process of establishing your
connections.
Complete the required configuration in
Google Cloud. First, create a redundant set of VLAN attachments in your
Virtual Private Cloud (VPC) network. Each VLAN attachment represents a logical connection between a
region in your VPC network and your OCI resources. Then, for
each VLAN attachment, use a Cloud Router to configure a Border Gateway Protocol (BGP) peering
session.
Follow the recommended steps to verify that your networks are connected.
You can also use Cross-Cloud Interconnect to connect to other cloud service providers.
For more information, see the
Supported cloud providers
section in the Cross-Cloud Interconnect overview.
