# AWS::NetworkManager::ConnectAttachment
<a name="aws-resource-networkmanager-connectattachment"></a>

Creates a core network Connect attachment from a specified core network attachment. 

A core network Connect attachment is a GRE-based tunnel attachment that you can use to establish a connection between a core network and an appliance. A core network Connect attachment uses an existing VPC attachment as the underlying transport mechanism.

For more information about using the `Ref` function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html).

## Examples
<a name="aws-resource-networkmanager-customergatewayassociation--examples"></a>



### Customer Gateway Association
<a name="aws-resource-networkmanager-customergatewayassociation--examples--Customer_Gateway_Association"></a>

The following example template creates a global network, device, customer gateway, VPN connection, and transit gateway. It registers the transit gateway in the global network, and creates an association between the customer gateway and device. The creation of the customer gateway association depends on the VPN connection and transit gateway registration.

## Return values
<a name="aws-resource-networkmanager-device-return-values"></a>

### Ref
<a name="aws-resource-networkmanager-device-return-values-ref"></a>

When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the IDs of the global network and device. For example: `global-network-01231231231231231|device-07f6fd08867abc123`.

For more information about using the `Ref` function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html).

### Fn::GetAtt
<a name="aws-resource-networkmanager-device-return-values-fn--getatt"></a>

The `Fn::GetAtt` intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the `Fn::GetAtt` intrinsic function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html).
