Getting started with AWS Global Networks for Transit Gateways for Transit Gateway networks

The following tasks help you become familiar with AWS Global Networks for Transit Gateways. For more information about how AWS Global Networks for Transit Gateways works, see How AWS Global Networks for Transit Gateways works.

In this example, you create a global network and register your transit gateway with the global network. You can also define and associate your on-premises network resources with the global network.

Prerequisites

Before you begin, ensure that you have a transit gateway with attachments in your account or in any account within your organization. For more information, see Getting Started with Transit Gateways.

The transit gateway can be in the same AWS account as the global network or in a different AWS account within the organization.

Step 1: Create a global network

Create a global network as a container for your transit gateway.

To create a global network

1. Open the Network Manager console at https://console.aws.amazon.com/networkmanager/home/.

2. Under Connectivity, choose Global Networks.

3. Choose Create global network.

4. Enter a name and description for the global network, and choose Create global network.

Step 2: Register your transit gateway

Register a transit gateway in your global network.

To register the transit gateway

1. Access the Network Manager console at https://console.aws.amazon.com/networkmanager/home/.

2. Under Connectivity, choose Global Networks.

3. On the Global networks page, choose the global network ID.

4. In the navigation pane, choose Transit gateways, and then choose Register transit gateway.

5. From the Select account dropdown list, choose the account that you want to register the transit gateway from.

   A list of transit gateways from that account appear in the Select transit gateway to register section.

6. Select one or more transit gateways from the list, and then choose Register transit gateway.

Step 3: (Optional) Define and associate your on-premises network resources

You can define your on-premises network by creating sites, links, and devices to represent objects in your network. For more information, see the following procedures:

• Create a site

• Creating a link

• Create a device

  You associate the device with a specific site, and with one or more links. For more information, see Associate a device.

On your transit gateway you can

• Create a Site-to-Site VPN connection attachment. For more information, see Customer gateway associations.

• Create a transit gateway Connect attachment, and then associate the Connect peer with the device. For more information, see Transit Gateway Connect peer associations.

You can also work with one of our Partners in the AWS Partner Network (APN) to provision and connect your on-premises network. For more information, see AWS Network Manager.

Step 4: (Optional) Enable multi-account access

Enable multi-account access to register transit gateways from multiple accounts, allowing you to view and manage transit gateways and associated resources from those registered accounts in your global network. Onboarding to AWS Organizations is a prerequisite for enabling multi-account access for Network Manager.

1. Create your organization using AWS Organizations.

   If you've already done this skip this step. For more information on creating an organization using AWS Organizations, see Creating and managing an organization in the AWS Organizations User Guide.

2. Enable multi-account on the Network Manager console.

   This enables trusted access for Network Manager and allows for registering delegated administrators. For more information enabling trusted access and registering delegated administrators, see Multi-account .

3. Create your global network.

   For more information on creating a global network, see Create a global network.

4. Register transit gateways.

   With multi-account enabled, you can register transit gateways from multiple accounts to your global network. For more information about registering transit gateways, see Transit gateway registrations.

Step 5: View and monitor your global network

The Network Manager console provides a dashboard for you to view and monitor both your transit gateway network objects in your global network.

To access the dashboard for your global network

1. Access the Network Manager console at https://console.aws.amazon.com/networkmanager/home/.

2. Under Connectivity, choose Global Networks.

3. On the Global networks page, choose the global network ID.

4. The Overview page provides an inventory of the objects in your global network for your transit gateway network. For more information about the pages in the dashboard, see Visualize transit gateway networks.
