  • [ACSA Education #28] MSTP Theory and Regional Structure

    A Common Spanning Tree (CST) defines a single Spanning Tree Instance for the entire network, regardless of the number of VLANs. All BPDUs use Untagged VLAN 1, so VLAN details are not considered. Additionally, due to the absence of load balancing, specifying alternative paths or achieving low line usage and potential performance degradation…

  • [ACSA Training #27] How RSTP Works

    RSTP (Rapid STP) operates a loop-free topology through the following algorithm: Selection of the Root Switch; Selection of the Root Port (RP) of all other non-root switches or non-designated bridge switches; Selection of the Designated Port (DP) of the links connecting each switch; Other ports operate in a blocked state to prevent loops; Root Switch…

    Continuing from last time, we will explore STP (Spanning Tree Protocol), specifically RSTP (Rapid STP). We will examine the key factors that the RSTP algorithm uses to determine which ports to use for traffic delivery and which not. Bridge Identifier Bridge Protocol Data Unit Rapid Spanning Tree Port States Rapid Spanning Tree Port Cost Rapid Spanning…

  • [ACSA Training #25] Spanning Tree Protocol

    Last time, while discussing network redundancy, we also talked about loops that can occur as a result. As an alternative, I briefly mentioned STP (Spanning Tree Protocol). Today, let's take a closer look at Spanning Tree Protocol. STP (Spanning Tree Protocol) Overview: IEEE 802.1d, the standard version of STP (Spanning Tree Protocol), [addresses] redundant environments…
