# 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).
