Spanning Tree Protocol (STP) Flashcards
What is the purpose of the Spanning Tree Protocol (STP)?
Purpose: Prevents network loops by creating a loop-free logical topology.
What is the standard for STP?
Standard: IEEE 802.1D.
What are the key features of STP?
Key Features: Slow convergence (up to 50 seconds) due to states like Listening and Learning
When is STP used?
Usage: Ensures a single active path between network switches.
What does PVST+ stand for and what is its purpose?
PVST+ (Per-VLAN Spanning Tree Plus): Allows each VLAN to have its own instance of STP.
What is the standard for PVST+?
Standard: Cisco proprietary.
What are the key features of PVST+?
Key Features: Separate spanning tree per VLAN, better load balancing, and redundancy.
When is PVST+ used?
Usage: Optimizes performance for networks with multiple VLANs.
What does RPVST+ stand for and what is its purpose?
RPVST+ (Rapid Per-VLAN Spanning Tree Plus): Combines the benefits of PVST+ with rapid convergence.
What is the standard for RPVST+?
Standard: Cisco proprietary, based on IEEE 802.1w (RSTP).
What are the key features of RPVST+?
Key Features: Fast convergence, separate instance per VLAN.
When is RPVST+ used?
Usage: Improves network efficiency and reduces downtime during topology changes.
What does MST stand for and what is its purpose?
MST (Multiple Spanning Tree): Maps multiple VLANs to a single spanning tree instance to optimize resource use.
What is the standard for MST?
Standard: IEEE 802.1s.
What are the key features of MST?
Key Features: Fewer spanning tree instances, more efficient use of resources.
