Rapid Per-VLAN Spanning Tree (RPVST+)
Rapid Spanning Tree may sound like a completely different version of the original spanning tree, but back in the early days when Rapid Spanning Tree was first being developed some people actually called it rapid reconfiguration of spanning tree. The goal wasn't to completely reengineer spanning tree, but to simply make it converge faster. The Rapid Spanning Tree specification is known as 802. 1w, and that's how Cisco refers to it. If you need help remembering this you can think of the w as standing for wow, like when you're riding on a really fast rollercoaster and you say wow, this is fun or scary. Okay, maybe you don't like rollercoasters, but use whatever works for you as long as it helps you remember that 802. 1w is Rapid Spanning Tree. Just like regular PVST+, rapid PVST+ gives you one instance of spanning tree per VLAN, but instead of running 802. 1D spanning tree, which is timer based, it runs 802. 1w Rapid Spanning Tree, which is not timer based. So to reiterate, when you configure Rapid Spanning Tree on a switch it still gives you one spanning tree instance per VLAN. In this module, we're going to cover three main topics, upgrading from the old regular spanning tree to Rapid Spanning Tree, the new port types or link types Rapid Spanning Tree uses and the port roles that Rapid Spanning Tree uses.
