@Generated(value="jsii-pacmak/1.84.0 (build 5404dcf)", date="2023-06-19T16:30:39.065Z") @Stability(Stable) public class CfnTransitGateway extends CfnResource implements IInspectable
A CloudFormation AWS::EC2::TransitGateway.

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.
