At deck with Radio Perlman, she developed what was known as the deck standard, and that was called a CSC, a common spanning tree. In fact, when the IAAA came out outside the standards - based version of 802.1D, that was also considered to be a common spanning tree. And what that means is that even if we have multiple VLANs configured on t hese switches and trunks between the switches, every VLAN is still going to be using the same instance of a spanning tree. In other words, for VLAN 100, 200, and 300, all of the different VLANs are going to be looking at the same switch as the root bridge. They’re going to have the same forwarding and blocking ports on the various switches. And later, Cisco came along and said, “Okay, let’s see if we can improve on that just a bit because we realize different VLANs by their nature have different traffic pa tterns.” Maybe for one VLAN, it would be better for switches to be the route. Maybe for another VLAN, SW - 2 could be the route. Maybe another VLAN would benefit from having SW3 as the route. It is not always possible to have a one - size - fits - all spanning tre e. So Cisco developed the PVST approach, the pervlin - spanning tree. And as the name suggests, each VLAN is going to have its own instance of a spanning tree. So for example, let’s say VLAN 100 uses switch SW1 as its root; another VLAN could use a different switch. And in the literature, you may see this written a couple of different ways. You may see it written as PVST or PVST plus. It’s typically fine to use those terms interchangeably, but I wanted to make sure you knew the difference. If you see a plus sign after PVST, that means the trunks interconnecting these switches are using the Q trunk encapsulation type, as opposed to Cisco’s ISL, which is a link - proprietary trunk encapsulation type. But typically, we just use those terms interchangeably. Now bac k to another standard approach to a spanning tree protocol: MSTP, or multiple spanning tree protocol. You may also see that written as just mist for multiple spanning tree protocol, and it is a standard; it’s II 802 1S.
