s300 vpls irb

В общем, я не знаю зачем я это сделал, но если вам нужен интегрированный роутинг на snr s300 вместе с vpls, то вопрос решается физической петлей между портами и следующим конфигом.

В итоге получаем связь со шлюзом и с порта 3, и с порта 4. Могло бы получится вообще клёво, если бы порты 40г были полнофункциональными, а так — баловство.
