    Associates an EC2 managed prefix list with a Network Manager Cloud WAN core network. Once associated, the prefix list can be referenced in the core network policy document.

    NOTE: The prefix list must be defined in the Cloud WAN home region (us-west-2). Although defined in the Cloud WAN home region, the prefix-list based policy will apply globally to all the relevant core network edges (regions) in your core network.

    Example Usage

    import * as pulumi from "@pulumi/pulumi";
    import * as aws from "@pulumi/aws";
    
    const prefixList = new aws.ec2.ManagedPrefixList("prefix_list", {

    • core_network_id (String) Core network ID.
    • prefix_list_arn (String) Prefix list ARN.

    Optional

    • account_id (String) AWS Account where this resource is managed.
