Cisco 7206 пропадание ip routinga

Всех с новым годом!

А нам Cisco сюрприз принесла, всё работало и вдруг инет отпал, захожу в консоль, а там запись no ip routin и маршрут интернета пропал.

Кто что может подсказать.

Интерфейс хоть не погас ? траффик и мас-адреса есть на входе ?

интерфейс не погас только no ip route-cache, трафик был не значительный 50 кбит/с маки не смотрел надо было запускать.

:) Угу, спрятал ip :) зная шлюз и маску /30 любой пионер посчитает ваш ip

С киски хоть шлюз пингуется ? А может просто инет выключили за неоплату.

Интернет у вас на железке есть - теперь попробуйте сформулировать проблему чуть более развернуто чем пропал ip routing.

да сейчас есть.

 

буквально 3 часа тому назад он не был, я зашёл на роутер и вижу в конфиге запись no ip routing на интерфейсах no ip route-cache нет маршрута в интернет (ip route xxx xxx xx), я это исправляю и инет возвращается.

А он и не пропадал, судя по 5-минутным счетчикам
