Доброго времени суток уважаемые специалисты.
Возникла вот такая вот проблема, перерыл много информации но для себя ответа не нашел, прошу судить не строга так, как только начинаю администрировать Cisco.
Суть :
Имеються два провайдера, при переключении на другого провайдера, в случае пропажи первого происходит crash.Crashinfo ^

Интерфейс валиться и идет переключение на другова провайдера, а тут 'clear ip nat trans forced' система уходит в ребут…
Замкнутый круг.
Вопрос следующий. Возможно ли исправить проблему падения цыски при 'clear ip nat trans forced' .
И можна ли по подробнее услышать о virtual reassembly, на даный момент его пришлось отключить на интерфейсе .
За ранние спасибо.
