In this episode you will learn:
- STP's primary function is to prevent Layer 2 loops by logically blocking redundant switch ports.
- The root bridge is elected based on the lowest Bridge ID (BID), which is a combination of a priority value and the switch's MAC address.
- Cisco's Per-VLAN Spanning Tree Plus (PVST+) runs a separate STP instance for each VLAN, enabling traffic load balancing.
- STP ports transition through five states: Disabled, Blocking, Listening, Learning, and Forwarding.
- Bridge Protocol Data Units (BPDUs) are the control messages used by switches to share topology information and elect the root bridge.
