During the implementation of Spanning Tree Protocol, all switches are rebooted by the network administrator. What is the first step of the spanning-tree election process?
- Each switch with a lower root ID than its neighbor will not send BPDUs.
- All the switches send out BPDUs advertising themselves as the root bridge.
- Each switch determines the best path to forward traffic.
- Each switch determines what port to block to prevent a loop from occurring.
| Answers Explanation & Hints:
After a Cisco switch boots, it will send out BPDUs containing its individual BID and the root ID for the network. By default, the initial root ID at bootup will be the ID of that individual switch. After a root bridge is elected, port states and paths are chosen. |
