Response

{'TransitGateway': {'Options': {'SecurityGroupReferencingSupport': 'enable | '
                                                                   'disable'}}}

Creates 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 CreateTransitGatewayVpcAttachment.

To attach a VPN connection, use CreateCustomerGateway to create a customer gateway and specify the ID of the customer gateway and the ID of the transit gateway in a call to CreateVpnConnection.

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 CreateTransitGatewayRouteTable 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 EnableTransitGatewayRouteTablePropagation to propagate routes from a resource attachment to a transit gateway route table. If you disable automatic associations, you can use AssociateTransitGatewayRouteTable to associate a resource attachment with a transit gateway route table.

Attaches the specified VPC to the specified transit gateway.

If you attach a VPC with a CIDR range that overlaps the CIDR range of a VPC that is already attached, the new VPC CIDR range is not propagated to the default propagation route table.

To send VPC traffic to an attached transit gateway, add a route to the VPC route table using CreateRoute.
