Create a peering attachment using Amazon VPC Transit Gateways

Before you begin, ensure that you have the ID of the transit gateway that you want to attach. If the transit gateway is in another AWS account, ensure that you have the AWS account ID of the owner of the transit gateway.

After you create the peering attachment, the owner of the accepter transit gateway must accept the attachment request.
