Google VXC Setup

Architecture

We will construct the following architecture on Google Cloud.

Prerequisites

VLAN Attachment

This step is performed on Google Parameters:

“Partner Interconnect Connection”
“Set up unencrypted Interconnect”

“Network”: Choose the one you are connecting from
“Region”: Choose the one that there is a Telnyx PoP in proximity
“MTU”: 8896

Create a router or choose an existing one.

Telnyx Network

This step is performed on Telnyx. If you don’t have a network created already, you may follow this guide to create one.

Procedure

Create a VXC resource

This step is performed on Telnyx.

POST /v2/virtual_cross_connects HTTP/1.1
Host: api.telnyx.com
Content-Type: application/json
Authorization: Bearer XXX
Content-Length: 286

{
    "network_id": "a843547c-3f08-4a7e-8a4b-270c3ffb13f2",
    "name": "xd-frankfurt-vxc-gcp",
    "cloud_provider": "gce",
    "cloud_provider_region": "europe-west3",
    "primary_cloud_account_id": "xxxx/europe-west3/2",
    "bgp_asn": 16550,
    "bandwidth_mbps": 50
}

Activate Connection

This step is performed on Google. “Peer ASN”: 63440 (Telnyx) “MD5 Authentication”: primary_bgp_key

Update BGP Peering

This step is performed on Telnyx. At this point, the connection is “Down”. We need to take the Google assigned GBP IPs and set them on the VXC. Use the PATCH method.

primary_cloud_ip — “Cloud Router BGP IP” or “Remote IP” in the “Troubleshooting” page
primary_telnyx_ip — “BGP peer IP” or “Local IP”in the “Troubleshooting” page

PATCH /v2/virtual_cross_connects/:vxc_uuid HTTP/1.1
Host: api.telnyx.com
Content-Type: application/json
Authorization: Bearer XXX
Content-Length: 31

{
    "primary_enabled": true,
    "primary_cloud_ip": "169.254.131.250/29",
    "primary_telnyx_ip": "169.254.131.249/29"
}

At this point, on Google, it will show the “Status” as “Up”

Validate Connection

This step is performed on Google.

Under VPC networks, you should see the routes advertised over the cloud router created.
You can also ssh in one of your instances in the same network and perform a traceroute.
