3:50 there must be a hub if I am not mistaken. But he said it correctly - Two links in one segment. So the switch4 has actually 2 ports connected to a hub and a hub is connected using 1 link to the switch3 From Cisco's official cert guide book: "The need for a backup port can be a bit confusing at first because the need for the backup port role only happens in designs that are a little unlikely today. The reason is that a design must use hubs, which then allows the possibility that one switch connects more than one port to the same collision domain With a backup port, if the current designated port fails, switch can start using the backup port with rapid convergence"
Hi Paul, I would like understand the BPDU details such as Topology change notification and configuration change - LSB and MSB in more details. Thanks for this video. Regards, Akshay
Very concise I’ll save this for a quick refresh when needed.

thanks for explaining. very good info.
