And I mentioned that this is a standard. Specifically, it’s III 802, one W. Oh, by the way, we talked about Cisco’s approach to PVST and PBST. Plus, they also came out with a variant of the Rapid Spanish Three Protocol, which they call Rapid PVST or Rapid PBST. Plus, they’re simply using their per - VLAN spanning tree approach, but they’re overlaying that with this RSTP standard. And to better understand a rapid spanning tree protocol, we need to define some terms. First, let’s consider some different roles that our ports may have. And the good news is, once we understand the port roles of a PVST topology as an example, then we’ll understand this pretty well. We still have the concept of a root bridge, which is the switch with the lowest bridge ID, which is made up of the bridge priority followed by the Mac address. We still have the concept of root ports. Remember, we have a route port and only one route port on every non - route bridge. So the root bridge has zero route ports, and that route port on the non - route bridge is the port on that bridge or switch that’s closest to the route. In terms of cost, we still have the concept of “designated ports.” Remem ber that every segment has a designated port. And you might wonder, hold on, what about that other link from switch three up to the hub, that shared media hub? That entire path from the switch up to the hub back down the other path — that’s one segment. So we do not have a designated port on that other link because it’s part of the same segment. We also have ports that are administratively shut down or disabled. Where it gets a little bit different, though, is when we have blocked ports. There are two types of blocking ports in the rapid spanning tree protocol. One is an alternate port that we would have on a switch. We’ve got a full duplex point - to - point connection between switch two and switch three. And if we’re blocking thanks to Spanish - 3 protocol decisi ons, then that’s going to be known as an alternate port. Another type of blocking port we might see, hopefully not, but on an Ethernet hub. Hopefully we do not have these in our network, but if we did and we had this loop up to the hub and back, obviously that’s a layer to loop. So we’re going to have one port blocked. But if we’re going through a shared media hub, instead of calling it an alternate port, we call it a backup port. Also, the different port states differ a bit with RSTP. We still have a situa tion where we’re throwing packets away.
