Если вам не составит труда, можете показать состояния бриджа(c VLAN) в котором срабатывает rstp и состояние mstp на коммутаторах, самому интересно.

Я то думал, вы решили попробовать без бриджевания ethernet, и с бриджевать только vlan (подобие MSTP)
так тоже работает, но сходимость при отказе одного из коммутаторов около 2,5 мин на автомате или скриптами вкл-вык физ.интерфейс.
