## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as mediaconnect_alpha from '@aws-cdk/aws-mediaconnect-alpha';
import { aws_ec2 as ec2 } from 'aws-cdk-lib';
import { aws_iam as iam } from 'aws-cdk-lib';

declare const flow: mediaconnect_alpha.Flow;
declare const networkInterface: mediaconnect_alpha.NetworkInterface;
declare const role: iam.Role;
declare const securityGroup: ec2.SecurityGroup;
declare const subnet: ec2.Subnet;
const bridgeFlowInput: mediaconnect_alpha.BridgeFlowInput = {
  name: 'name',
  source: {
    flow: flow,

    // the properties below are optional
    vpcInterface: {
      name: 'name',
      role: role,
      securityGroups: [securityGroup],
      subnet: subnet,

      // the properties below are optional
      networkInterfaceIds: ['networkInterfaceIds'],
      networkInterfaceType: networkInterface,
    },
  },
};
```
