This document will provide instructions, technical details and guidelines for integrating a Google Cloud environment with the Telnyx network backbone. A virtual cross connect (VXC) is a private and direct connection between cloud providers that is faster and safer than a traditional public internet connection. Using this strategy allows you to bypass the internet and gain direct and private access to Telnyx, thereby eliminating hops and reducing the risk of packet loss and jitter. You’ll also benefit from the additional security of direct interconnection.
Note: To protect against man in the middle attacks, we always recommend that you encrypt both signaling and media with TLS & Z/SRTP.
Instructions for integrating Google VPC with Telnyx
In this activity you will:
GCP Virtual Private Cloud (VPC) network
For optimal performance, your VPC needs to be located in the same region where you plan to build a Virtual Cross Connect (VXC)
Coming soon! Check back frequently as we are updating our documentation.
1. Create a GPC Partner Interconnect and VLAN attachments
In this step, you'll create a GPC partner interconnect, which will connect your Google Cloud VPC to the Telnyx network. You will then create VLAN attachments which are connections between your local routers and Google Cloud's routers used by your partner interconnect.
Open the Google Cloud Platform VPC.
Choose Interconnect Type -> Partner Interconnect
Under Add Partner VLAN Attachment -> Check your connection, choose I already have a service provider.
Under Add VLAN attachments, fill in the following:
Redundancy: Telnyx recommends selecting Create a redundant pair of VLAN attachments. See pricing for each Virtual Cross Connect here. Note that a redundant pair of VLAN attachments requires two VXCs.)
VPC network: default
Region: The region should be the same region where you’re running the software application.
Cloud Router: The router will be created in the same region as your VPC Network.
Name the VLAN attachment(s): Consider a naming convention similar to us-east-4-vlan-attachment-1 (i.e.: country-region-etc)
Now select OK to connect your VPC networks.
Click on VLAN Attachment Detail and copy your pairing key(s). You will need them
2. Provide Telnyx with VXC Preferences
In this step, you'll let Telnyx know your VXC preferences for a network and a site. The network uses virtual routing and forwarding technology to provide you with a unique routing table within Telnyx's routers. A site is a Telnyx Point of Presence (PoP) where we house our network gear.
Log into your Telnyx Mission Control Portal.
Go to the Networking section.
Click Create New Network to create a new one.
If you have one you want to use, click View Details for this network.
Find the Site Detail section of your network and click Add Site(s), then Create VXC to create a new site.
If you have a site you want to use, click Create VXC on an existing site.
Note that you should select sites that are local to your Google Cloud region(s). See a list of Telnyx sites and their corresponding local Google Cloud regions.
Select Google Cloud as your Cloud Provider.
Select Bandwidth Speed.
Input your Google Pairing Key for you primary VLAN attachment. (i.e., the last number of the pairing key should be "1") You can retrieve this from https://console.cloud.google.com/hybrid/interconnects, and by viewing VLAN Attachment Detail. They key will be in the format <random>/<vlan-attachment-region>/<edge-availability-domain>
If you created a redundant link, click Secondary Link and input your Google Pairing Key from the secondary VLAN Attachment (i.e., the last number of the pairing key should be "2")
Review New Virtual Cross Connect (VXC) Request. Click Create VXC.
3. Activate the Virtual Cross Connect in Google Cloud
Now that everything is configured, let's activate your VXC in Google Cloud.
Open the Google Cloud Platform VPC at https://console.cloud.google.com/hybrid/interconnects/.
For each VLAN Attachment under Actions, Click Activate. (This option may take up to 5 minutes to appear.) Then Click Accept
For each VLAN Attachment under Actions, Click Configure BGP.
In EDIT BGP session, in the Peer ASN field, input 63440. Click Save and Continue.
Click Refresh. Status should say Up.
Copy the Cloud Router IP for each VLAN Attachment. You will need this in the next step.
4. Complete your Order in Telnyx
Copy the Cloud Router IP for the first VLAN Attachment. Click Save. If you have a redundant link, copy the Cloud Router IP for the second VLAN Attachment. Click Save.
Telnyx will approve your request (this may take up to 3 hours). Order Status will change from Pending to Active to Complete. Once an Order Status is complete, the BGP session between Telnyx and Google Cloud will be active.
To receive traffic from Telnyx, your cloud hosts must have public IP addresses configured. Consult your Telnyx representative before clicking 'Enable' if you need assistance.
Under routing status, click the button to enable. Doing this will transition packet delivery from your Cloud Provider's Internet transit to the private Virtual Cross Connect resulting in a brief traffic disruption.
That's it, you've now integrated your Google VPC and Telnyx though VXC.
