@Generated(value="jsii-pacmak/1.116.0 (build 0eddcff)", date="2025-10-24T13:34:49.827Z") @Stability(Experimental) public class TransitGateway extends Resource implements ITransitGateway, IRouteTarget
(experimental) Creates a Transit Gateway.

Example: 

 TransitGateway transitGateway = new TransitGateway(this, "MyTransitGateway");
 ITransitGatewayRouteTable routeTable = transitGateway.addRouteTable("CustomRouteTable");
 VpcV2 myVpc = new VpcV2(this, "Vpc");
 SubnetV2 subnet = SubnetV2.Builder.create(this, "Subnet")
         .vpc(myVpc)
         .availabilityZone("eu-west-2a")
         .ipv4CidrBlock(new IpCidr("10.0.0.0/24"))
         .subnetType(SubnetType.PUBLIC)
         .build();
 ITransitGatewayVpcAttachment attachment = transitGateway.attachVpc("VpcAttachment", AttachVpcOptions.builder()
         .vpc(myVpc)
         .subnets(List.of(subnet))
         .build());
 // Associate an attachment with a route table
 routeTable.addAssociation("Association", attachment);
 // Enable route propagation for an attachment
 routeTable.enablePropagation("Propagation", attachment);

    • addRouteTable

      @Stability(Experimental) @NotNull public ITransitGatewayRouteTable addRouteTable(@NotNull String id)
      (experimental) Adds a new route table to the Transit Gateway.

      Parameters:
      id - This parameter is required.
      Returns:
      The created Transit Gateway route table.

    • attachVpc

      @Stability(Experimental) @NotNull public ITransitGatewayVpcAttachment attachVpc(@NotNull String id, @NotNull AttachVpcOptions options)
      (experimental) Attaches a VPC to the Transit Gateway.

      Parameters:
      id - This parameter is required.
      options - This parameter is required.
      Returns:
      The created Transit Gateway VPC attachment.

    • getDefaultRouteTable

      @Stability(Experimental) @NotNull public ITransitGatewayRouteTable getDefaultRouteTable()
      (experimental) The default route table associated with the Transit Gateway.

      This route table is created by the CDK and is used to manage the routes for attachments that do not have an explicitly defined route table association.

      Specified by:
      getDefaultRouteTable in interface ITransitGateway

    • getDefaultRouteTableAssociation

      @Stability(Experimental) @NotNull public Boolean getDefaultRouteTableAssociation()
      (experimental) Indicates whether new attachments are automatically associated with the default route table.

      If set to true, any VPC or VPN attachment will be automatically associated with the default route table unless otherwise specified.

      Specified by:
      getDefaultRouteTableAssociation in interface ITransitGateway

    • getDefaultRouteTablePropagation

      @Stability(Experimental) @NotNull public Boolean getDefaultRouteTablePropagation()
      (experimental) Indicates whether route propagation to the default route table is enabled.

      When set to true, routes from attachments will be automatically propagated to the default route table unless propagation is explicitly disabled.

      Specified by:
      getDefaultRouteTablePropagation in interface ITransitGateway

    • getDnsSupport

      @Stability(Experimental) @NotNull public Boolean getDnsSupport()
      (experimental) Whether or not DNS support is enabled on the Transit Gateway.
      Specified by:
      getDnsSupport in interface ITransitGateway

    • getRouterTargetId

      @Stability(Experimental) @NotNull public String getRouterTargetId()
      (experimental) The ID of the route target.
      Specified by:
      getRouterTargetId in interface IRouteTarget

    • getRouterType

      @Stability(Experimental) @NotNull public RouterType getRouterType()
      (experimental) The type of router used in the route.
      Specified by:
      getRouterType in interface IRouteTarget

    • getSecurityGroupReferencingSupport

      @Stability(Experimental) @NotNull public Boolean getSecurityGroupReferencingSupport()
      (experimental) Whether or not security group referencing support is enabled on the Transit Gateway.

      getSecurityGroupReferencingSupport in interface ITransitGateway

    • getTransitGatewayArn

      @Stability(Experimental) @NotNull public String getTransitGatewayArn()
      (experimental) The Amazon Resource Name (ARN) of the Transit Gateway.

      The ARN uniquely identifies the Transit Gateway across AWS and is commonly used for permissions and resource tracking.

      Specified by:
      getTransitGatewayArn in interface ITransitGateway

    • getTransitGatewayId

      @Stability(Experimental) @NotNull public String getTransitGatewayId()
      (experimental) The unique identifier of the Transit Gateway.

      This ID is automatically assigned by AWS upon creation of the Transit Gateway and is used to reference it in various configurations and operations.
