Bases: BaseLoadBalancerProps

Properties for a network load balancer.

Parameters:

  • vpc (IVpc) – The VPC network to place the load balancer in.

  • cross_zone_enabled (Optional[bool]) – Indicates whether cross-zone load balancing is enabled. Default: - false for Network Load Balancers and true for Application Load Balancers. This can not be false for Application Load Balancers.

  • deletion_protection (Optional[bool]) – Indicates whether deletion protection is enabled. Default: false

  • deny_all_igw_traffic (Optional[bool]) – Indicates whether the load balancer blocks traffic through the Internet Gateway (IGW). Default: - false for internet-facing load balancers and true for internal load balancers

  • internet_facing (Optional[bool]) – Whether the load balancer has an internet-routable address. Default: false

  • load_balancer_name (Optional[str]) – Name of the load balancer. Default: - Automatically generated name.

  • vpc_subnets (Union[SubnetSelection, Dict[str, Any], None]) – Which subnets place the load balancer in. Default: - the Vpc default strategy.

  • client_routing_policy (Optional[ClientRoutingPolicy]) – The AZ affinity routing policy. Default: - AZ affinity is disabled.

  • enforce_security_group_inbound_rules_on_private_link_traffic (Optional[bool]) – Indicates whether to evaluate inbound security group rules for traffic sent to a Network Load Balancer through AWS PrivateLink. Default: true

  • ip_address_type (Optional[IpAddressType]) – The type of IP addresses to use. If you want to add a UDP or TCP_UDP listener to the load balancer, you must choose IPv4. Default: IpAddressType.IPV4

  • security_groups (Optional[Sequence[ISecurityGroup]]) – Security groups to associate with this load balancer. Default: - No security groups associated with the load balancer.

  • zonal_shift (Optional[bool]) – Indicates whether zonal shift is enabled. Default: false
