Free CCNA | Rapid STP | Day 22 Lab | CCNA 200-301 Complete Course

Introduction

This tutorial guides you through setting up and analyzing a Rapid Spanning Tree Protocol (RSTP) topology using the command line interface (CLI). This is particularly relevant for those preparing for the CCNA 200-301 exam, as it covers fundamental networking concepts essential for managing network switches and preventing loops.

Step 1: Understand RSTP Basics

• What is RSTP?

  • Rapid Spanning Tree Protocol is an evolution of the original Spanning Tree Protocol (STP) designed to provide faster convergence.

• Key Benefits of RSTP:

  • Quickly responds to topology changes, reducing downtime.
  • Enhances network reliability by preventing loops.

• Common Terms:

  • Bridge: A device (like a switch) that connects two or more network segments.
  • Port Roles: Includes Root Port, Designated Port, and Alternate Port, which determine how a port behaves in the topology.

Step 2: Set Up Your Lab Environment

• Download Packet Tracer:

  • Visit the Cisco NetAcad website to download and install Packet Tracer if you haven’t already.

• Create a New Project:

  • Open Packet Tracer and start a new project.

• Add Devices:

  • Drag and drop three switches onto the workspace.
  • Connect the switches using Ethernet cables.

Step 3: Configure RSTP on the Switches

• Access the CLI:

  • Click on a switch and select the CLI tab to enter command mode.

• Enable RSTP:

  • Enter the following command to enable RSTP:

    Switch(config)# spanning-tree mode rapid-pvst
    

• Verify Configuration:

  • Use the command below to check if RSTP is active:

    Switch# show spanning-tree
    

  • Look for the RSTP information including root bridge ID and port states.

Step 4: Analyze the Topology

• Check the Spanning Tree Status:

  • Use the command:

    Switch# show spanning-tree
    

  • Review the output for:
    • Root Bridge details
    • Port states (Forwarding, Blocking)

• Simulate a Topology Change:

  • Disconnect one switch from the network and observe the changes in the spanning tree.
  • Use the same show spanning-tree command to see how RSTP adapts.

Step 5: Utilize Boson NetSim for Further Practice
