# FailoverConfigurationProps

Properties for failover Router Input configuration.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/router-input.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-mediaconnect-alpha/lib/router-input.ts#L727)

## Example

```ts
declare const stack: Stack;
declare const networkInterface: RouterNetworkInterface;

const input = new RouterInput(stack, 'FailoverInput', {
  routerInputName: 'failover-input',
  maximumBitrate: Bitrate.mbps(10),
  routingScope: RoutingScope.REGIONAL,
  tier: RouterInputTier.INPUT_20,
  configuration: RouterInputConfiguration.failover({
    networkInterface: networkInterface,
    protocols: [
      RouterInputProtocol.rist({
        port: 5000,
        recoveryLatency: Duration.millis(1000),
      }),
      RouterInputProtocol.rist({
        port: 5002, // Must not be consecutive with primary port
        recoveryLatency: Duration.millis(1000),
      }),
    ],
    sourcePriority: SourcePriorityConfig.primarySecondary(PrimarySource.FIRST_SOURCE),
  }),
});
```

## Properties

- `availabilityZone`: string — The availability zone where the router input is located.

  **Default:** assigned by the MediaConnect service

- `networkInterface`: [IRouterNetworkInterface](/cdk/api/v2/docs/@aws-cdk_aws-mediaconnect-alpha.IRouterNetworkInterface.html) (required) — Network interface for the Router Input.

- `protocols`: [RouterInputProtocol](/cdk/api/v2/docs/@aws-cdk_aws-mediaconnect-alpha.RouterInputProtocol.html)[] (required) — Array of exactly 2 protocol configurations for failover (must be same protocol type).

- `sourcePriority`: [SourcePriorityConfig](/cdk/api/v2/docs/@aws-cdk_aws-mediaconnect-alpha.SourcePriorityConfig.html) = SourcePriorityConfig.none() — Source priority configuration for failover.
