Creating MCR Connections to Google Cloud Services

Megaport makes it easy to provision fast, secure, and private connections between a customer’s data center and Google Cloud Platform.

Partner Interconnect

Partner Interconnect accesses the private address space (RFC 1918).

As part of the Google Cloud Interconnect (GCI) Partner program, Megaport provides users with dedicated access to Google Cloud Platform (GCP) and enables customers to create private connections between their remote network environments and their Virtual Private Cloud (VPC) deployments.

The benefits of creating GCI Partner Connections with Megaport include:

  • Enhanced security and higher network performance
  • Connectivity reach beyond Google’s existing network locations
  • Scalable connectivity for those who do not require the full bandwidth of Google’s Dedicated Interconnect
  • Savings on egress traffic costs from the customer’s VPC network to their on-premises network
  • API integration between Megaport and Google Cloud which simplifies the provisioning of connections for a fast and seamless experience
  • Layer 3 routing capabilities without having a physical router located in a data center

When connecting to Google Cloud Platform (GCP) through Partner Interconnect with Megaport, the Virtual Cross Connect (VXC) forms the Layer 2 component of the connection and Layer 3 BGP is established directly between the customer and GCP. Through Partner Interconnect, a customer can access VMs (Virtual Machines) built within a VPC.

Creating a VXC to the Google Cloud Platform

Before you begin, create a Megaport Cloud Router (MCR). If you don’t have an MCR, create one following the procedures in Creating an MCR.

To deploy a VXC to Google Cloud Platform

  1. Log in to your Google Cloud Console and create a pairing key.
  2. From the main menu in the Console, select Hybrid Connectivity > Interconnect.

  3. Click Get Started.

  4. Select Partner Interconnect and click Continue.

  5. Click I already have a service provider.

  6. Configure your attachment.

    Provide these attachment details:

    • Redundancy - Select a redundancy option. You can create redundant attachments or a single attachment.

    • VPC Network - Select the VPC network you want the VPC to connect.

    • Region - Select the region where your attachment will connect.

    • Cloud Router - Select a Cloud Router to associate with this attachment. You can only select a Cloud Router in the VPC network and region that you selected with an ASN of 16550. If you don’t have an existing Cloud Router, create one with an ASN of 16550. For redundancy, each VLAN attachment must be associated with a unique Cloud Router. Google automatically adds an interface and a BGP peer on the Cloud Router.

    • VLAN attachment name - Enter the VLAN attachment name using lowercase letters only.

    • Description - Optionally, enter a description for the attachment.

  7. Click Create.
    A pairing key appears.

  8. Copy the pairing key and click OK.

  9. In the Megaport Portal, create a VXC to your Google peering location: click +Connection on the MCR for your VXC.
    Create a VXC to Google location

  10. Click the Cloud tile.

  11. Select Google as the provider.

  12. Copy and paste the pairing key from the Google Cloud console into the field in the right-hand panel.
    The relevant Google targets appear based on the region of your GCI Partner connection.

  13. Select the target location for your first connection and click Next.
  14. Provide these connection details:

    • Name Your Connection - This is a free text field allowing you to assign an easily identifiable name for this connection.

    • Rate Limit - Enter the same rate you selected for your Google port speed.

  15. Click Next.

  16. Review the Summary and click Next.

  17. Click Add VXC and configure further VXCs or proceed through the ordering process.

After placing the order, wait a few minutes until the VXC status changes from red to green. Green indicates Layer 2 connectivity has been established.
Layer 2 connectivity

This completes your Layer 2 VXC deployment.

After the VXC is established in the Megaport Portal, you need to accept the attachment in the the Google Cloud Console and configure BGP. Google provides you with a private IP address to configure BGP.

Note

The Google ASN will always be 16550.

Google recommends implementing a redundant solution. If you want to deploy a second GCI partner connection, you need to create a second attachment in the Google Console, copy the new pairing key into the Megaport Portal, and repeat these steps.

For details, see the Google documentation on Google Partner Interconnects.

To activate and accept the connection

  1. In Google Console, return to the attachment you just created. The attachment status should be Activation needed. If the status shows Pending partner, refresh your screen or wait a couple of minutes until it changes to Activation needed.

  2. Click Activate.

    Google asks you to accept the connection.

  3. Click Accept and wait about a minute.

    The status updates to BGP configuration needed.

To configure BGP

  1. In Google Console, click Configure BGP.
    Configure BGP

  2. By default, the ASN assigned to the MCR is 133937. Leave the default peer ASN or enter a private ASN. Assign an MCR peer

  3. Click Save and Continue.

Wait a few minutes for the BGP peer to establish and then verify the BGP configuration.

To verify the BGP configuration

  1. In the Megaport Portal, select the VXC.

  2. Select the Logs tab.

    The VCX status should be BGP Established.

  3. In the Google Cloud Console, view the VLAN attachment. The status should be BGP Up.

For details, see the Google documentation on Viewing Router Status and Advertised Routes.
