Default configuration of SAP Spartacus routing parameters

I defined a routing parameter in the custom module with the following code:

 ConfigModule.withConfig({
      routing: {
        routes: {
          product: {
            paths: [
              'jerrycamera/:manufacturer/:name/:productCode',
              'cameras/:name/:productCode'],
            paramsMapping: {
              name: 'nameForUrl'
            }
          }
        }
      }
    } as RoutingConfig)
