Multi-Region Multicloud Transit Gateway Peering Workflow

Aviatrix Transit Gateway Peering connects two or more Aviatrix Transit Gateways in a partial or full-mesh manner for communication between groups of Spoke VPCs or VNets across multiple clouds and regions, as shown in the diagram below.

The Aviatrix Transit Gateways may be deployed in AWS or Azure, where each Transit Gateway connects a group of Spoke VPCs/VNets. As a result of Transit Gateway Peering, two groups of Spoke VPCs/VNets can communicate with each other via the Transit Gateways.

Creating Transit Gateway Peering Connection

To create Transit Gateway peering, do the following:

  1. Create the Transit Gateways

    If you have not created the Transit Gateways, then follow the instructions for creating a Transit Gateway in the Multicloud Transit Network workflow.

    Aviatrix High Performance Encryption (HPE) mode is supported on Transit Gateway Peering. To enable Transit Gateway Peering HPE, you must create the Transit Gateways with HPE mode enabled.

  2. Establish the Transit Gateway Peering

    To create a Transit Gateway peering:

    1. In CoPilot, go to Cloud Fabric > Gateways > Transit Gateways tab.

    2. Locate the Transit Gateway for which you want to create the peering, and click the Edit icon on its right.

    3. From the Peer to Transit Gateways dropdown menu, select the Transit Gateway you want to add as peering.

      You can select multiple Transit Gateways to create multiple peering connections.

    4. Click Save.

You can view the Transit Gateway’s peering connections by going to Cloud Fabric > Gateways > Transit Gateways tab. Select the Transit Gateway to open the Gateway Instance page, then go to Connections > Transit-Transit Peering tab. All transit-to-transit peering connections display in the table.
