@Generated(value="jsii-pacmak/1.116.0 (build 0eddcff)", date="2025-10-24T13:34:49.790Z") @Stability(Experimental) public interface AttachVpcOptions extends software.amazon.jsii.JsiiSerializable
(experimental) Options for creating an Attachment via the attachVpc() method.

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());
 // Add a static route to direct traffic
 routeTable.addRoute("StaticRoute", attachment, "10.0.0.0/16");
 // Block unwanted traffic with a blackhole route
 routeTable.addBlackholeRoute("BlackholeRoute", "172.16.0.0/16");

  • Method Details

    • getSubnets

      @Stability(Experimental) @NotNull List<ISubnet> getSubnets()
      (experimental) A list of one or more subnets to place the attachment in.

      It is recommended to specify more subnets for better availability.

    • getVpc

      @Stability(Experimental) @NotNull IVpc getVpc()
      (experimental) A VPC attachment(s) will get assigned to.

    • getAssociationRouteTable

      @Stability(Experimental) @Nullable default ITransitGatewayRouteTable getAssociationRouteTable()
      (experimental) An optional route table to associate with this VPC attachment.

      Default: - No associations will be created unless it is for the default route table and automatic association is enabled.

    • getPropagationRouteTables

      @Stability(Experimental) @Nullable default List<ITransitGatewayRouteTable> getPropagationRouteTables()
      (experimental) A list of optional route tables to propagate routes to.

      Default: - No propagations will be created unless it is for the default route table and automatic propagation is enabled.

    • getTransitGatewayAttachmentName

      @Stability(Experimental) @Nullable default String getTransitGatewayAttachmentName()
      (experimental) Physical name of this Transit Gateway VPC Attachment.

      Default: - Assigned by CloudFormation.

    • getVpcAttachmentOptions

      @Stability(Experimental) @Nullable default ITransitGatewayVpcAttachmentOptions getVpcAttachmentOptions()
      (experimental) The VPC attachment options.

      Default: - All options are disabled.

    • builder

      @Stability(Experimental) static AttachVpcOptions.Builder builder()
      Returns:
      a AttachVpcOptions.Builder of AttachVpcOptions
