# BridgeNetworkSource

Bridge network source options.

Extends: BridgeNetworkSource
Used as props by: BridgeSourceConfiguration

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/shared.ts`](https://github.com/aws/aws-cdk/blob/v2.276.0-alpha.0/packages/@aws-cdk/aws-mediaconnect-alpha/lib/shared.ts#L225)

## Example

```ts
declare const stack: Stack;

const productionNetwork = GatewayNetwork.define({
  cidrBlock: '192.168.1.0/24',
  name: 'production-network',
});

const gateway = new Gateway(stack, 'MyGateway', {
  gatewayName: 'my-gateway',
  egressCidrBlocks: ['10.0.0.0/16'],
  networks: [productionNetwork],
});

const ingressBridge = new Bridge(stack, 'MyIngressBridge', {
  bridgeName: 'my-ingress-bridge',
  config: BridgeConfiguration.ingress({
    maxBitrate: Bitrate.mbps(10),
    maxOutputs: 2,
    networkSources: [{
      name: 'on-prem-source',
      source: {
        protocol: BridgeProtocol.RTP,
        network: productionNetwork,
        multicastIp: '239.1.1.1',
        port: 5000,
      },
    }],
  }),
  gateway: gateway,
});
```

## Properties

- `multicastIp`: string (required) — The network source multicast IP.

  Must be a valid Multicast IP address.

- `multicastSourceIp`: string — The setting related to the multicast source.

  **Default:** no multicast source IP

  The IP address of the source for source-specific multicast (SSM).

- `network`: [GatewayNetwork](/cdk/api/v2/docs/@aws-cdk_aws-mediaconnect-alpha.GatewayNetwork.html) (required) — The gateway network this source listens on.

  Use {@link GatewayNetwork.define} to create the network and pass the same
  instance to the gateway and to each source that uses it.

- `port`: number (required) — The network source port.

- `protocol`: [BridgeProtocol](/cdk/api/v2/docs/@aws-cdk_aws-mediaconnect-alpha.BridgeProtocol.html) (required) — The network source protocol.
