Jeremy’s IT Lab - CCNA Course Overview

Introduction

• Free complete course for CCNA certification.
• Encouragement to subscribe to the channel, like, comment, and share videos.
• Recommendation to download the practice lab and try it in packet tracer.
• Suggestion to use Boson’s NetSim for hands-on practice.

Rapid Spanning Tree Protocol (RSTP) Lab

Step 1: Identifying the Root Bridge

• All switches have a priority of 32769 (32768 + 1 for VLAN1).
• SW1 has the lowest MAC address and is the root bridge.
• Normally all interfaces on the root bridge are designated ports.
• Exception: If two interfaces connect to the same collision domain, one is a backup port.

Step 2: Port Roles and States Without CLI

• SW2: F0/1 is the root port (root cost 19).
• SW3: F0/2 is the root port (root cost 19).
• SW4: F0/1 is the root port (SW3 has a lower bridge ID).
• Designated Ports:
  • SW3’s F0/1 is designated.
  • SW2’s G0/1 is designated (lower root cost than SW4).
• Alternate Ports:
  • SW2’s G0/1 and SW4’s F0/2 are alternate ports in a discarding state.

Configuration Verification

• SW1: Designated ports - F0/2, F0/1, F0/24; Backup discarding - F0/3.
• SW2: Root - F0/1; Designated - F0/2; Alternate - G0/1.
• SW3: Root - F0/2; Designated - G0/1, F0/1.
• SW4: Root - F0/1; Alternate - F0/2.

Step 3: RSTP Link Type Configuration

• SW4:
  • F0/1 and 2 as point-to-point.
  • F0/24 enabled portfast (edge).
• SW3:
  • F0/1 and G0/1 as point-to-point.
  • F0/2 (connected to hub) as shared.
• SW2:
  • All ports point-to-point by default.
  • Enable portfast on F0/23 and 24.
• SW1:
  • Shared: F0/2, 3, and 24 (connected to hub).
  • Point-to-point: F0/1.

Boson NetSim Lab Preview

Overview

• Demonstrating spanning tree labs from NetSim for CCNP ENCOR.
• Labs include tasks beyond just the spanning tree configuration.

Task 1: VLAN Configuration

• Verify IP configurations on PCs.
• Configure Switch1, Switch2, and Switch3 with VLANs and trunk ports.
• Verify connectivity with ping.

Task 2 & 3

• Configure the router with dot1q encapsulation.
• Observe spanning tree behavior.

Grading and Solutions

• Use grading function to check lab completion.
• Access lab solutions for command guidance and explanations.
