# GatewayBridgeSource

Options for Gateway Bridge Source.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/flow-source-configuration.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-mediaconnect-alpha/lib/flow-source-configuration.ts#L421)

## Example

```ts
declare const stack: Stack;
declare const bridge: Bridge;
declare const role: iam.IRole;
declare const securityGroup: ec2.ISecurityGroup;
declare const subnet: ec2.ISubnet;

const vpcInterface = VpcInterface.define({
  vpcInterfaceName: 'bridge-interface',
  role: role,
  securityGroups: [securityGroup],
  subnet: subnet,
});

const flow = new Flow(stack, 'MyFlow', {
  source: SourceConfiguration.gatewayBridge({
    bridge: bridge,
    vpcInterface: vpcInterface,
  }),
  vpcInterfaces: [vpcInterface],
});
```

## Properties

- `bridge`: [IBridge](/cdk/api/v2/docs/@aws-cdk_aws-mediaconnect-alpha.IBridge.html) (required) — The bridge feeding this flow.

- `vpcInterface`: [VpcInterfaceConfig](/cdk/api/v2/docs/@aws-cdk_aws-mediaconnect-alpha.VpcInterfaceConfig.html) — The VPC interface attachment to use for this bridge source.

  **Default:** no VPC interface
