🌳Spanning Tree Protocol (STP) prevents loops by electing a root bridge and blocking ports.
🔗STP determines the best path to the root bridge based on port cost, bridge ID, and priority.
🌐Different types of STP include standard STP, PVST, and RSTP with advantages like VLAN support and faster convergence.
🕒STP convergence time can be reduced by adjusting timers like hello, max age, and forward delay.
⚙️PVST allows per VLAN spanning trees for efficient network planning and management.
What is the purpose of Spanning Tree Protocol (STP)?
—STP prevents loops in network topologies with redundant connections, ensuring stable network operation.
How does STP determine the best path to the root bridge?
—STP considers factors like port cost, bridge ID, priority, and neighbor ports to select the best path to the root bridge.
What are the different types of STP and their benefits?
—The main types of STP include standard STP, PVST, and RSTP. PVST allows per VLAN spanning trees for efficient network planning and management, while RSTP offers faster convergence.
What can be done to minimize STP convergence time?
—Adjusting timers like hello, max age, and forward delay can reduce STP convergence time, ensuring faster network recovery after topology changes.
What is PVST and how does it benefit network management?
—PVST (Per VLAN Spanning Tree) allows the creation of separate spanning trees for each VLAN, providing efficient network planning and management.
