## Properties

- `description`: string — The description of the scope.

- `externalAuthorityConfiguration`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnIPAMScope.IpamScopeExternalAuthorityConfigurationProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.CfnIPAMScope.IpamScopeExternalAuthorityConfigurationProperty.html) — The configuration that links an Amazon VPC IPAM scope to an external authority system.

  It specifies the type of external system and the external resource identifier that identifies your account or instance in that system.

  For more information, see [Integrate VPC IPAM with Infoblox infrastructure](https://docs.aws.amazon.com/vpc/latest/ipam/integrate-infoblox-ipam.html) in the *Amazon VPC IPAM User Guide* .

- `ipamId`: string (required) — The ID of the IPAM for which you're creating this scope.

- `tags`: [CfnTag](/cdk/api/v2/docs/aws-cdk-lib.CfnTag.html)[] — The key/value combination of a tag assigned to the resource.

  Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key `Owner` and the value `TeamA` , specify `tag:Owner` for the filter name and `TeamA` for the filter value.
