Добрый день,
На CiSCO 1841 поднято два PPPoE соединения с одним провайдером. Оба соединения со статическими адресами. На втором соединении поднят туннель (с другой CiSCO-й в другом городе). При физическом выключении одного из соединений (выключается конвертор из E1 в Ethernet) перестает работать передача по туннелю, идущему по второму соединению с интернетом. В чем может быть ошибка?
