Based on the output from your switches, answer the following questions: Which switch is the root bridge
The output from a switch is the process of forwarding a packet from one port to another port on the same switch or to another network device. The switch uses the MAC address of the destination device to determine the correct port to forward the packet to.
To choose the root bridge on a switch, the switch uses a protocol called the Spanning Tree Protocol (STP). The STP algorithm selects one switch in the network to be the root bridge, which is the central point for the network topology. The root bridge is responsible for sending out bridge protocol data units (BPDUs) and determining the best path for data to travel through the network.
To choose the root bridge, the switch uses a process called the election process, in which the switch with the lowest bridge ID (BID) is chosen as the root bridge. The BID is a combination of the switch's MAC address and a configurable priority value. The switch with the lowest BID is chosen as the root bridge and the other switches in the network will adjust their paths to forward traffic through the root bridge.
You can choose the root bridge in the switch by configuring the switch's priority value. A lower priority value will increase the chances of the switch being elected as the root bridge.
The answer has to be general since the question is incomplete.
