# AWS::MediaConnect::RouterNetworkInterface
<a name="aws-resource-mediaconnect-routernetworkinterface"></a>

 The `AWS::MediaConnect::RouterNetworkInterface` resource defines how the router communicates with the outside world. Each router I/O needs a network interface, which determines how the router I/O connects to other resources and what security measures protect the connection. 

You can work with two types of router network interface:
+ **Public network interfaces** - allow communication over the public internet.
+ **VPC network interfaces** - allow communication within your Amazon Virtual Private Cloud (VPC).

## Syntax
<a name="aws-resource-mediaconnect-routernetworkinterface-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

## Return values
<a name="aws-resource-mediaconnect-routernetworkinterface-return-values"></a>

### Ref
<a name="aws-resource-mediaconnect-routernetworkinterface-return-values-ref"></a>

When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the router network interface ARN. For example:

 `{ "Ref": "arn:aws:mediaconnect:us-west-2:111122223333:routerNetworkInterface:00e8efe67aa3" }` 

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-mediaconnect-routernetworkinterface-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).
