• Download the practice lab and try it in packet tracer.
• Recommended tool: Boson’s NetSim for CCNA for more detailed labs and instructions.

Network Access Section Labs

• Configuring VLANs
• Deleting VLANs
• VTP (to be covered in day 18’s lecture video)
• VLAN configuration, trunking
• Preview of a relevant lab at the end of the video
• Link in the description to purchase NetSim
• NetSim is highly recommended for CCNP preparation as well

Lab Overview: VLAN Configuration and Trunking

• Lab using Packet Tracer
• Focus: Configure VLANs and VLAN trunking (From Day 17’s lecture video)

Step 1: Configure Switch Interfaces (SW1 & SW2)

SW1 Configuration

• Access ports for VLAN10:
  • INTERFACE RANGE F0/1 to 2
  • SWITCHPORT MODE ACCESS
  • SWITCHPORT ACCESS VLAN 10
• Access ports for VLAN30:
  • INTERFACE RANGE F0/3 to 4
  • SWITCHPORT MODE ACCESS
  • SWITCHPORT ACCESS VLAN 30

SW2 Configuration

• VLAN20:
  • INTERFACE F0/1
  • SWITCHPORT MODE ACCESS
  • SWITCHPORT ACCESS VLAN 20
• VLAN10:
  • INTERFACE RANGE F0/2 to 3
  • SWITCHPORT MODE ACCESS
  • SWITCHPORT ACCESS VLAN 10

Step 2: Configure Trunk Between SW1 and SW2

• SW1 Trunk Configuration:
  • INTERFACE G0/1
  • SWITCHPORT TRUNK: No encapsulation option needed (only DOT1Q supported)
  • SWITCHPORT MODE TRUNK
  • SWITCHPORT TRUNK ALLOWED VLAN 10,30
  • SWITCHPORT TRUNK NATIVE VLAN 1001
• Verify VLANs:
  • DO SHOW VLAN BRIEF
  • Ensure VLANs 10 and 30 are present
• SW2 Trunk Configuration: Identical to SW1
  • Create missing VLAN30:
    • VLAN 30

Step 3: Router On A Stick (SW2 & R1 Configuration)

SW2 Trunk Configuration

• Allow all three VLANs: INTERFACE G0/2
  • SWITCHPORT MODE TRUNK
  • SWITCHPORT TRUNK ALLOWED VLAN 10,20,30
  • SWITCHPORT TRUNK NATIVE VLAN 1001

Router R1 Configuration

• Enable interface:
  • INTERFACE G0/0
  • NO SHUTDOWN
• VLAN10 Subinterface:
  • INTERFACE G0/0.10
  • ENCAPSULATION DOT1Q 10
  • IP ADDRESS 10.0.0.62 255.255.255.192
• VLAN20 Subinterface:
  • INTERFACE G0/0.20
  • ENCAPSULATION DOT1Q 20
  • IP ADDRESS 10.0.0.126 255.255.255.192
• VLAN30 Subinterface:
  • INTERFACE G0/0.30
  • ENCAPSULATION DOT1Q 30
  • IP ADDRESS 10.0.0.190 255.255.255.192

Step 4: Testing Connectivity

• Ping from PC7 to other PCs:
  • PING 10.0.0.1 (PC in VLAN10)
  • PING 10.0.0.65 (PC in VLAN20)
  • PING 10.0.0.129 (PC in VLAN30)

Boson NetSim Preview

• Lab: Inter-VLAN Routing 1
  • Similar topology: One router, two switches, and PCs
  • Tasks Overview: Configure switch and PCs, Subinterfaces, Verify connectivity

Task 1: Basic Network Connectivity Configuration

Steps

1. Verify IP configurations on PC1 and PC2
   • PC1: 192.168.100.2, subnet mask /25, gateway .1
   • PC2: 192.168.100.130, subnet mask /25, gateway .129
2. Configure Switch1 hostname
   • ENABLE
   • CONF T
   • HOSTNAME Switch1
3. Verify and create VLANs on Switch1
   • Check VLANs: DO SHOW VLAN BRIEF
   • Create VLANs: VLAN 10 and VLAN 12
4. Discover PC connection ports (via MAC Address)
   • Check MAC Address on PC1: IPCONFIG /ALL
   • Check MAC Address on Switch1: SHOW MAC-ADDRESS-TABLE
   • Identify ports for PC1 and PC2
5. Add PCs to correct VLANs on Switch1
   • INTERFACE F0/3, SWITCHPORT MODE ACCESS, SWITCHPORT ACCESS VLAN 10
   • INTERFACE F0/4, SWITCHPORT MODE ACCESS, SWITCHPORT ACCESS VLAN 12
6. Verify configuration on Switch1: DO SHOW VLAN BRIEF
7. Ping test (expected to fail due to lack of inter-VLAN routing)
   • PING 192.168.100.130

Task Completion and Grading

• Grade lab: Will highlight any missing configurations.
