public interface NetworkLoadBalancerAttributes

Properties to reference an existing load balancer.

Example:

 // Create an Accelerator
 Accelerator accelerator = new Accelerator(this, "Accelerator");
 // Create a Listener
 Listener listener = accelerator.addListener("Listener", ListenerOptions.builder()
         .portRanges(List.of(PortRange.builder().fromPort(80).build(), PortRange.builder().fromPort(443).build()))
         .build());
 // Import the Load Balancers
 INetworkLoadBalancer nlb1 = NetworkLoadBalancer.fromNetworkLoadBalancerAttributes(this, "NLB1", NetworkLoadBalancerAttributes.builder()
         .loadBalancerArn("arn:aws:elasticloadbalancing:us-west-2:111111111111:loadbalancer/app/my-load-balancer1/e16bef66805b")
         .build());
 INetworkLoadBalancer nlb2 = NetworkLoadBalancer.fromNetworkLoadBalancerAttributes(this, "NLB2", NetworkLoadBalancerAttributes.builder()
         .loadBalancerArn("arn:aws:elasticloadbalancing:ap-south-1:111111111111:loadbalancer/app/my-load-balancer2/5513dc2ea8a1")
         .build());
 // Add one EndpointGroup for each Region we are targeting
 listener.addEndpointGroup("Group1", EndpointGroupOptions.builder()
         .endpoints(List.of(new NetworkLoadBalancerEndpoint(nlb1)))
         .build());
 listener.addEndpointGroup("Group2", EndpointGroupOptions.builder()
         // Imported load balancers automatically calculate their Region from the ARN.
         // If you are load balancing to other resources, you must also pass a `region`
         // parameter here.
         .endpoints(List.of(new NetworkLoadBalancerEndpoint(nlb2)))
         .build());
