@Generated(value="jsii-pacmak/1.127.0 (build 2117ad5)", date="2026-03-11T13:19:58.727Z") @Stability(Stable) public class CfnTransitGatewayPropsMixin extends Mixin implements software.constructs.IMixin
Specifies a transit gateway.

You can use a transit gateway to interconnect your virtual private clouds (VPC) and on-premises networks. After the transit gateway enters the available state, you can attach your VPCs and VPN connections to the transit gateway.

To attach your VPCs, use AWS::EC2::TransitGatewayAttachment .

To attach a VPN connection, use AWS::EC2::CustomerGateway to create a customer gateway and specify the ID of the customer gateway and the ID of the transit gateway in a call to AWS::EC2::VPNConnection .

When you create a transit gateway, we create a default transit gateway route table and use it as the default association route table and the default propagation route table. You can use AWS::EC2::TransitGatewayRouteTable to create additional transit gateway route tables. If you disable automatic route propagation, we do not create a default transit gateway route table. You can use AWS::EC2::TransitGatewayRouteTablePropagation to propagate routes from a resource attachment to a transit gateway route table. If you disable automatic associations, you can use AWS::EC2::TransitGatewayRouteTableAssociation to associate a resource attachment with a transit gateway route table.

To create a transit gateway with EncryptionSupport enabled through CloudFormation, you will need the ec2:ModifyTransitGateway Identity and Access Management (IAM) permission. For more information, see ModifyTransitGateway in Actions, resources, and condition keys for Amazon EC2 of the Identify and Access Management Service Authorization Reference .
