Схема:
Важно:
Отключать spanning-tree до узлов. Он может блокировать линки.
Настраивать одинаковый route-target both 100:100, чтобы была маршрутизация между nvi.
На узлах настроен более точный маршрут 20.1.1.0/24 [1/0] via 10.1.1.1, до основного шлюза, а не 0.0.0.0. Потому что пинг может быть не стабилен если много DG настроено.
