Три одинаковых Mikrotik, двое ходят в интернет по резервному каналу, третий - нет?

korsar182, не помогло, к сожалению - придется ехать и включать вручную локально)
есть какие-то адекватные методы тестирования этих гипотез?
пинг и трассировка не подходят, потому что пинг и трассировка проходят, но выхода в интернет на резервном канале, при отключении основного, все равно нет

Три одинаковых Mikrotik, двое ходят в интернет по резервному каналу, третий - нет?

это сделает проверку пинга правильной и рекурсивным станет маршрут до рлайн (основного), а не сумтел - спасибо, исправил
но я не понимаю, как убрать интерфейсы с бриджа и каким образом это должно починить выход в интернет через резервный канал

Три одинаковых Mikrotik, двое ходят в интернет по резервному каналу, третий - нет?

Ruslan-Strannik, по этим адресам мониторится, есть ли интернет за шлюзом, чтобы Микротик переключал тогда, когда за шлюзом инета нет, а не только когда сам шлюз отвалится
рекурсия реализована только у одного провайдера, тк внешний айпи только у одного провайдера берется на каждой локации

они все disabled на роутере А - там маркировка выключена или не доделана, как я понял
