Creating a Google Cloud Services Connection for an MVE with Versa Secure SD-WAN
You can create a network connection from an MVE with Versa Secure SD-WAN to Google Cloud through Partner Interconnect.
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.
Before you begin, create an MVE in Versa Director. For details, see Creating an MVE. The MVE needs to be in the active state.
There are three parts to adding a Google Cloud connection to your MVE and Versa Director.
Create a Partner Interconnect attachment in Google Cloud Console or gcloud CLI. Copy the pairing key that is provided as part of the attachment creation. For additional details, see the Google documentation on Google Partner Interconnects.
In the Megaport Portal, create a VXC from your MVE to connect to your Google Cloud attachment.
In Versa Director, create a new interface and add the details of the Google Cloud connection.
These instructions step through the second and third parts.
MVE for Versa Secure SD-WAN requires configuration steps in both Versa Director and the Megaport Portal for all cloud connections.
Adding the Google Cloud connection in the Megaport Portal
To set up the Google Cloud Platform connection, you need to create the connection in the Megaport Portal.
To deploy a VXC to GCP from the Megaport Portal
In the Megaport Portal, click +Connection on the MVE to create your VXC.
Click the Cloud tile.
Select Google as the provider.
Copy and paste the pairing key from the Google Cloud console into the field in the right-hand pane.
The relevant Google targets appear based on the region of your GCI Partner connection.
- Select the target location for your connection and click Next.
Provide these connection details:
Connection Name – 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.
Preferred A-End VLAN – This is the VLAN for this connection that you will receive through the MVE. This must be a unique VLAN ID on this MVE and can range from 2 to 4093. If you specify a VLAN ID that is already in use, the system displays the next available VLAN number. The VLAN ID must be unique to proceed with the order. If you don’t specify a value, Megaport will assign one.
Add the VXC to your order and complete the checkout process.
Once you have deployed the VXC, go back to your attachment in the Google Cloud Console and accept the attachment.
You will be provided your private IP address from Google to configure BGP.
Ensure that you pre-activate the attachment or mark the attachment as active after configuring the VXC. Otherwise, you cannot set up BGP with your SD-WAN instance.
The Google ASN will always be 16550.
Adding the Google Cloud connection to Versa Director
After you create the connection from your MVE to Google Cloud and set up the connection in the Google console, you need to configure it in Versa Director. This involves configuring BGP settings, ASNs, and VLANs.
To add the Google Cloud connection in Versa Director
Collect the connection details from the Google console.
Display the details of the connection you created in Google Cloud for this connection. Note the values for the Peer ASN, Cloud Router BGP IP, and BGP Peer IP.
Collect the connection details from the Megaport Portal.
Click the gear icon for the Google connection from your MVE and click the Details view. Note the value for the A-End VLAN.
Next, you will add a subinterface to your Versa MVE instance.
Log in to Versa Director.
Select the Workflows tab in the top menu bar.
- Select Template > Templates in the left menu bar.
- Select the template you want to edit, then select the Interfaces tab.
- Under WAN Interfaces, click the Add icon to add a subinterface.
- Provide the following information:
- VLAN ID – Enter the A-End VLAN value for this Google connection in the Megaport Portal. Click the Details icon for the connection in the Portal to find this value.
- Network Name – Choose +Create WAN Network from the dropdown to open the Create WAN Network window. Specify a meaningful name for the network, click OK, and then select the WAN network you created. (Or, if appropriate for your environment, select an existing network name.)
- IPv4 – Choose Static from the dropdown to assign a static IP address to this subinterface.
We have finished creating the interface. Next we need to create the BGP session.
- Select the Routing tab to add the BGP configuration information.
- In the BGP section, choose the network created earlier.
- Enter the following values for your connection:
- Local AS – This is the Peer ASN value from the VLAN attachment details in the Google Cloud console.
- Neighbor IP – This is the local Google Cloud IP address. This value is available in the VLAN attachment details in the Google Cloud console. The IP address appears in the Cloud Router BGP IP field.
- Peer AS – This is the Google Cloud ASN of 16550. This is a fixed value, and appears in the connection details on the Google console.
- Optionally, enable BFD (as appropriate for your network).
- Click the Add icon.
- Click Recreate.
A screen appears that shows the differences in the configuration. The auto-merged version is recommended, and selected by default.
- Click Deploy.
At this point, we have updated the template assigned to the device group. Next, we will parameterize variables to generate routing information dynamically.
To parameterize the configuration variables
- Select the Configuration tab in the top menu bar.
- Select Templates > Device Templates in the horizontal menu bar.
- Click the template you want to modify.
By default, the Interfaces column appears.
- In the side navigation, select Virtual Routers, and click the link for the subinterface network to open the Edit window.
- In the side navigation, select BGP, then click the Instance ID for your network.
- In the Edit BGP Instance window, click the Parameterize icon next to each of the following fields: Router ID, Local AS, Peer AS, and Password.
- Click OK two times to update.
Next we need to configure the device and create the BGP session.
To update parameterized variables for a device
- Select the Workflows tab in the top menu bar.
- Select Devices > Devices in the horizontal menu bar.
- Click the device to modify.
- Select the Bind Data tab.
All parameterized values are displayed here.
- Enter the following values for the variables:
- Local AS number – The Customer ASN in the Megaport Portal.
- MD5 password – The BGP Auth Key in the Megaport Portal.
- BGP Peer AS – 16550, the Google Cloud ASN.
- BGP Router ID – The Customer IP address (your local IP address) from the MVE details.
- Next Hop Address – The Cloud Router BGP IP from the VLAN attachment details in the Google Cloud console.
- Interfaces with Mask – The static IP address of the interface on the Megaport side of the connection, including the mask value.
- Click Deploy to create the new configuration for the device. When the new configuration for the device has completed successfully, a green checkmark appears at the bottom of the Director window.
- In the upper right of the screen under your username, click Commit Template to push the changes to the device.
- Specify the following values:
- Organization – Select your organization from the dropdown.
- Select Template – Select your template to display its associated devices in the table.
- Differences – Click the eye icon in the Differences column to view the configuration to be applied to the device.
- If you are satisfied with the configuration, click Commit to Device.
A green checkmark appears at the bottom right of the screen when the push is successful. The Template State and Appliance State are now IN_SYNC with the device.
- Close the window.
Validating your Google Cloud connection
You can review device status, including the connection state, from the Monitor tab in Director.
- Select the Monitor tab in the top menu bar.
- Select Devices in the horizontal menu bar.
- Click the device to view status and activity.
In the Summary screen you can review your subinterface in the Interface column, and the Operational and Admin Status.
- Return to Google Cloud Platform and refresh to see the new virtual interface.
