Всем привет, проблем такая
запускаю схему на стенде влан на абонента:
[DGS-3120]
Код:
+---------------[DES-3200-18]-----+
| (1) |
------8 uplink----- [DGS-3120] |
| (2) |
+---------------[DES-3200-18]-----+
кольцевые коммутаторы без qinq, агрегатор DGS-3120 - селективный qinq (все порты в NNI mode, 8 порт в UNI c трансляциями )
суть проблемы - при настройке qinq на агрегаторе сломался rstp, коммутаторы по rstp друг друга не видят:
