Last reviewed 2023-08-27 UTC

This document discusses how to use Equinix Network Edge and Partner Interconnect to deploy private, multi-cloud connectivity between Google Cloud Virtual Private Cloud (VPC) networks and Oracle® virtual cloud networks (VCNs).

This document is intended for cloud network engineers and operation professionals who want to interconnect their Google Cloud environment to an Oracle Cloud environment. It assumes that you're familiar with Virtual Private Cloud. It also assumes that you have a basic understanding of the following concepts:

  • Networking architecture
  • Configuring Google Cloud and Oracle Cloud
  • Equinix Platform solutions
  • Cisco CSR1000V settings

In this document the Cisco CSR1000V router is used as an Equinix Network Edge vRouter.

Architecture

To connect your cloud networks between Google Cloud and Oracle Cloud through private connections, find a colocation facility where both cloud providers meet. This document uses the Equinix colocation facility located in Ashburn, Virginia.

For more information about colocation facilities with private connections to multiple cloud providers, see Equinix Fabric.

The following diagram shows the network architecture described in this document.

Data flowing from a Virtual Private Cloud, to a colocation facility, and finally to an Oracle
Cloud instance.

The previous diagram displays how data from a Virtual Private Cloud routes through a colocation facility on its way to an Oracle Cloud instance.

There are various network architecture designs and considerations for production and non-production usages. This document discusses how to create redundant connections using a Cloud Router and Partner Interconnect through a pair of redundant Equinix Network Edge virtual routers (vRouters) to Oracle Cloud VCNs.

For more information on other network designs and considerations, see Cloud Dedicated and Partner Interconnect Service Level Agreement (SLA) and Google Cloud redundancy and SLA.

Create a pair of Google Partner VLAN attachments

For Equinix to create a VLAN attachment on your behalf on your Virtual Private Cloud, you need to create a pairing key. To create that key, complete the following steps:

  1. In the the Google Cloud console menu, under Networking,
    select Hybrid Connectivity, then Interconnect.
  2. Select Partner Interconnect, then click Continue.
  3. Select I already have a service provider.
  4. On the Add Partner VLAN attachment page, select Create a redundant pair of VLAN attachments (recommended).
  5. Select the proper Network and Region to locate your Virtual Private Cloud for VLAN attachments. In this deployment, use us-east4 (Virginia) to Oracle Cloud at Equinix location Ashburn.
  6. For VLAN A, select Create new router, name your Cloud Router, then click Create.
    • Name your VLAN A attachment, and choose an MTU. The Cloud Router ASN of 16550 is assigned by Google Cloud.
  7. For VLAN B, select the Cloud Router you created for VLAN A, then name your VLAN B attachment. Choose the same MTU as VLAN A.
  8. Click Create.
  9. Copy the pairing keys for later use at the Equinix Fabric portal.

A pair of VLAN attachments are created with a pairing key for each. The ending digit of the pairing key, either /1 or /2, indicates the edge availability domain zone (zone 1 or zone 2) that the VLAN attachment belongs to. The process in the next section uses the pairing key of edge availability domain zone 1 to create the first VLAN attachment from Google Cloud over Partner Interconnect.

For more information, see pairing keys.
