Метрика таблицы маршрутизации Omnet++ OSPF

Вопрос 1: я реализовал протокол ospf в Omnet++. В соответствии с топологией r1 может достигать r3 двумя разными способами. Я установил метрику верхнего пути на 1 и нижнего пути на 10. Однако, согласно протоколу OSPF, он не должен выбирать нижний путь, но всегда выбирает нижний путь, а затем возврат к верхнему пути. Как видно из таблицы маршрутизации, есть проблема со значениями метрик.

Вопрос 2: мне нужно увидеть таблицу маршрутизации в консоли. Я использовал метод printRoutingTable() для его печати, но он не работает.

Вопрос 3. Как просмотреть таблицу состояния ссылок, чтобы узнать всю топологию?
