Gateway associations in AWS Global Networks for Transit Gateways
Create a customer gateway association with either a device or with a transit gateway Connect peer.
Customer gateway associations
To add your on-premises network to your global network, you associate a customer gateway with your device, and optionally, a link. The customer gateway must already be in your global network as part of a VPN attachment in your transit gateway. If you specify a link, it must already be associated with the specified device.
For more information about creating a customer gateway, see Create a Customer Gateway in the AWS Site-to-Site VPN User Guide. For more information about creating a VPN attachment to a transit gateway, see Transit Gateway VPN Attachments in Amazon VPC Transit Gateways.
For more information about viewing the topology of your on-premises network in Network Manager, see Access transit gateway network dashboards using AWS Network Manager />.
Transit Gateway Connect peer associations
You can associate a Transit Gateway Connect peer (in a transit gateway Connect attachment) with a device, and optionally, with a link.
If you specify a link, it must be associated with the specified device.
