Các anh cho em hỏi trong thời gian Hold-down mà vẫn forward gói tin tới mạng đích đang được giữ hold-down .Theo em hiểu thì nếu mạng đích trong tình trạng up/down thì ta cứ gửi gói tin đến ,gói tin vẫn có khả năng tới đích được .
cụ thể cirriculum:Routers still forward packets to destination networks that are marked as possibly down. This allows the router to overcome any issues associated with intermittent connectivity. If the destination network truly is unavailable and the packets are forwarded, black hole routing is created and lasts until the holddown timer expires
