WebAug 11, 2024 · Spanning Tree Protocol is a Layer 2 protocol that helps to prevent loops in a network by creating a logical tree that spans all of the switches in a network. STP works by electing a root switch, and then all other switches in the network calculate the shortest path to the root switch. STP then blocks any redundant paths to prevent loops. 3. WebThe root bridge will be the switch with the: Lowest bridge ID The port closest to the root bridge in terms of least overall cost (best path) to the root bridge is the: Root port The port on the segment (with two switches) that has the lowest path cost to the root bridge is the: Designated port

This will set the bridge priority to 28672, which is lower than the default priority but higher than the root primary. When the primary switch fails, the switches will elect a new root bridge. It will then failover to the secondary switch, and it will be elected as the new root bridge. core sports uk
