# AWS::MediaConnect::RouterInput MergeRouterInputConfiguration
<a name="aws-properties-mediaconnect-routerinput-mergerouterinputconfiguration"></a>

Configuration settings for a merge router input that combines two input sources.

## Syntax
<a name="aws-properties-mediaconnect-routerinput-mergerouterinputconfiguration-syntax"></a>

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

### JSON

```
{
  "[MergeRecoveryWindowMilliseconds](#cfn-mediaconnect-routerinput-mergerouterinputconfiguration-mergerecoverywindowmilliseconds)" : Integer,
  "[NetworkInterfaceArn](#cfn-mediaconnect-routerinput-mergerouterinputconfiguration-networkinterfacearn)" : String,
  "[ProtocolConfigurations](#cfn-mediaconnect-routerinput-mergerouterinputconfiguration-protocolconfigurations)" : [ MergeRouterInputProtocolConfiguration, ... ]
}
```

### YAML
<a name="aws-properties-mediaconnect-routerinput-mergerouterinputconfiguration-syntax.yaml"></a>

```
  [MergeRecoveryWindowMilliseconds](#cfn-mediaconnect-routerinput-mergerouterinputconfiguration-mergerecoverywindowmilliseconds): Integer
  [NetworkInterfaceArn](#cfn-mediaconnect-routerinput-mergerouterinputconfiguration-networkinterfacearn): String
