# BridgeFailoverConfig

Source failover configuration for a bridge.

Bridges only support `FAILOVER` (switchover) mode — the `MERGE` mode available on
`Flow.sourceFailoverConfig` is not allowed on bridges by the service. Use
{@link BridgeFailoverConfig.failover} to construct the configuration.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/bridge.ts`](https://github.com/aws/aws-cdk/blob/v2.274.0-alpha.0/packages/@aws-cdk/aws-mediaconnect-alpha/lib/bridge.ts#L328)

## 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';
const bridgeFailoverConfig = mediaconnect_alpha.BridgeFailoverConfig.failover(/* all optional props */ {
  primarySource: 'primarySource',
  state: mediaconnect_alpha.State.ENABLED,
});
```

## Methods

- `failover(options?: BridgeFailoverOptions): BridgeFailoverConfig // chainable` (static) — Configure switchover-mode failover.

  The bridge swaps to the backup source when
  the primary source stops receiving data.
