Introduction This post is inspired by a post at IEOC about Uplinkfast and TCN which can be found here. Before we get to those parts, let’s recap how Ethernet and STP work together. Spanning Tree The Spanning Tree Algorithm builds
Spanning tree convergence
Someone asked the other day how fast STP converges depending on PVST+ or RPVST+ or MST is running. Usually the answer for PVST+ is 30-50 seconds and for RPVST+ it’s fast, maybe less than a second. I thought I would
