This section provides an overview of relevant labs in the network access section. It mentions VLAN configuration and trunking as topics covered in previous lectures.

Relevant Labs

Labs related to VLAN configuration and trunking are located in the network access section.

Specific labs include configuring VLANs, deleting VLANs, and VTP (to be covered in day 18's lecture video).

Lab Preview: Configuring VLAN Trunking

This section previews a lab that focuses on configuring VLAN trunking. It encourages viewers to stick around until the end of the video for more details.

Lab Preview

The lab will cover configuring VLAN trunking.

The same network topology used in Day 17's lecture video will be used with slightly changed IP addresses.

Detailed steps will be provided during the lab demonstration.

Step 1: Configuring Access Ports on SW1

This section covers step 1 of the lab, which involves configuring access ports on SW1 for specific VLANs.

Step 1: Configure Access Ports on SW1

Enter privileged exec mode with ENABLE, then global config mode with CONFIGURE TERMINAL.

Configure PC interfaces connected to SW1 as access ports in the correct VLAN.

For VLAN10: INTERFACE RANGE F0/1 to 2, SWITCHPORT MODE ACCESS, SWITCHPORT ACCESS VLAN 10.

For VLAN30: INTERFACE RANGE F0/3 to 4, SWITCHPORT MODE ACCESS, SWITCHPORT ACCESS VLAN 30.

Step 1: Configuring Access Ports on SW2

This section covers step 1 of the lab for SW2, which involves configuring access ports for specific VLANs.

Step 1: Configure Access Ports on SW2

Enter privileged exec mode with ENABLE, then global config mode with CONFIGURE TERMINAL.

Configure PC interfaces connected to SW2 as access ports in the correct VLAN.

For VLAN20: INTERFACE F0/1, SWITCHPORT MODE ACCESS, SWITCHPORT ACCESS VLAN 20.

For VLAN10: INTERFACE RANGE F0/2 to 3, SWITCHPORT MODE ACCESS, SWITCHPORT ACCESS VLAN 10.

Step 2: Configuring Trunk and Native VLAN

This section covers step 2 of the lab, which involves configuring the connection between SW1 and SW2 as a trunk and setting up the native VLAN.

Step 2: Configure Trunk and Native VLAN

Return to SW1 and enter privileged exec mode with ENABLE.

Configure the connection between SW1 and SW2 as a trunk.

Allow only necessary VLANs on the trunk.

Set an unused VLAN as the native VLAN.

Check if all necessary VLANS exist on each switch.

Troubleshooting VLAN30 Traffic Issue

This section addresses a problem with VLAN30 traffic not being received on the trunk between SW1 and SW2.

Troubleshooting VLAN30 Traffic Issue

Check the output of DO SHOW INTERFACES TRUNK to identify the issue.

The management domain displays only VLAN10, indicating that VLAN30 doesn't exist on SW2.

Verify if all necessary VLANS exist on each switch using DO SHOW VLAN BRIEF.

The summary has been provided in English as requested.

Configuration on SW2

This section focuses on the configuration of SW2, specifically the G0/2 trunk. All three VLANs (10, 20, 30) need to be allowed.

Configure G0/2 as a trunk interface.

Allow VLANs 10, 20, and 30 on the trunk.

Set VLAN 1001 as the native VLAN.

Configuration on R1

This section covers the configuration of R1, including enabling interfaces and configuring subinterfaces for VLANs.

Enter privileged exec mode with ENABLE and then enter global config mode with CONF T.

Enable G0/0 interface by using NO SHUTDOWN.

Configure subinterface for VLAN10: G0/0.10.

Set encapsulation to DOT1Q with ENCAPSULATION DOT1Q 10.

Assign IP address 10.0.0.62/26 to the subinterface.

Configure subinterface for VLAN20: G0/0.20.

Set encapsulation to DOT1Q with ENCAPSULATION DOT1Q 20.

Assign IP address 10.0.0.126/26 to the subinterface.

Configure subinterface for VLAN30: G0/0.30.

Set encapsulation to DOT1Q with ENCAPSULATION DOT1Q 30.

Assign IP address 10.0.0.190/26 to the subinterface.

Explanation of Router Address Choice

This section explains why it is recommended to use either the first or last usable address in a subnet as the router's address.

It is important to have consistency across the network when choosing a gateway address for a subnet.

Using a random address for the router can make it difficult to understand and manage a large network.

Configuration of VLAN20's Subinterface

This section focuses on the configuration of VLAN20's subinterface on R1.

Configure subinterface for VLAN20: G0/0.20.

Set encapsulation to DOT1Q with ENCAPSULATION DOT1Q 20.

Assign IP address 10.0.0.126/26 to the subinterface.

Configuration of VLAN30's Subinterface

This section covers the configuration of VLAN30's subinterface on R1.

Configure subinterface for VLAN30: G0/0.30.

Set encapsulation to DOT1Q with ENCAPSULATION DOT1Q 30.

Assign IP address 10.0.0.190/26 to the subinterface.

Testing Connectivity - Ping from PC7

In this section, connectivity between PCs is tested using pings from PC7.

Ping PC1 in VLAN10 (IP: 10.0.0.1).

The ping is successful as PC7 and PC1 are in the same VLAN and subnet.

No inter-VLAN routing is required.

Testing Connectivity - Ping from PC7 (VLAN20)

This section continues testing connectivity by pinging PC5 in VLAN20 from PC7.

Ping PC5 in VLAN20 (IP: 10.0.0.65).

The ping is successful, but it requires routing through R1 before reaching SW2 and then PC5.

The reply follows the same path back.

Testing Connectivity - Ping from PC7 (VLAN20)

This section concludes the connectivity testing by pinging PC3 in VLAN20 from PC7.

Ping PC3 in VLAN20 (IP: 10.0.0.129).

The ping is successful, but it requires routing through R1 before reaching SW2, SW1, and then PC3.

The reply follows the same path back.

Introduction to Boson NetSim Preview

This section introduces the Boson NetSim preview lab for Inter-VLAN Routing 1.

A lab preview is shown with a brief overview of the lab topology.

Command summaries and IP addresses on each device are provided.

Lab Tasks Overview

This section provides an overview of the lab tasks for Inter-VLAN Routing 1 in Boson NetSim.

Task 1: Configure the switch and PC hosts.

Task 2: Configure subinterfaces.

Task 3: Complete and verify connectivity.

Each task has multiple sub-tasks/steps.

Lab Preview - Task 1: Configuring Switch and PCs

This section focuses on Task 1 of the lab preview, which involves configuring basic network connectivity on Switch1, PC1, and PC2.

Step 1: Verify current IP configurations on PC1 and PC2 to match the IP addresses table.

Use IPCONFIG /ALL command to check IP configurations.

Ensure correct IP addresses, subnet masks, and default gateways are set for each PC.

Lab Preview - Task 2: Configuring Switch Hostname

This section covers Step 2 of Task 1 in the lab preview, which involves configuring Switch1's hostname.

Access the CLI of Switch1.

Change the default hostname to an appropriate name.

Introduction and VLAN Configuration

In this section, the speaker discusses the default VLAN configuration and the steps to create VLANs 10 and 12. The speaker also explains how to discover which ports PC1 and PC2 are connected to on Switch 1.

Creating VLANs

By default, all ports are in VLAN1.

VLANs 10 and 12 do not exist initially.

To create VLAN10:

Enter VLAN 10 command.

To create VLAN12:

Enter EXIT command.

Press the up arrow key.

Discovering Port Connections

Look for the "Physical Address" (MAC address) of PC1 and PC2.

On Switch1, check the MAC address table using SHOW MAC-ADDRESS-TABLE command.

Note that some devices may use SHOW MAC ADDRESS-TABLE instead of hyphens.

Find the last four digits of the physical address (e.g., 3538).

The switch has learned that PC1 is connected to port FastEthernet0/3.

Find the last four digits of PC2's physical address (e.g., 6059).

PC2 is connected to port FastEthernet0/4.

Configuration Verification

This section focuses on verifying the configuration by checking VLAN assignments for PCs and ensuring they are correct.

Verifying Configuration

Use SHOW VLAN BRIEF command on Switch1 to verify configurations.

Confirm that FastEthernet0/3 is assigned to VLAN10 (connected to PC1).

Confirm that FastEthernet0/4 is assigned to VLAN12 (connected to PC2).

Ping Failure and Inter-VLAN Routing

The speaker explains why the ping between PC1 and PC2 fails and discusses the absence of inter-VLAN routing configuration.

Ping Failure

Issue a ping command from PC1 to PC2 (PING 192.168.100.130).

The pings fail because the PCs are in separate VLANs and require inter-VLAN routing.

Check for trunk interface configuration on Switch1 using SHOW INTERFACES TRUNK command.

FastEthernet0/1 is not configured as a trunk.

Inter-VLAN Routing

Check if any subinterfaces are configured on Router1 using SHOW IP INTERFACE BRIEF command.

No subinterfaces are configured, indicating that inter-VLAN routing (router-on-a-stick) is not set up.

The absence of inter-VLAN routing configuration causes the ping failure.

Conclusion

The speaker concludes by mentioning two remaining tasks: configuring subinterfaces and verifying connectivity. They also provide additional resources for lab solutions.

Remaining Tasks

Configuring subinterfaces and verifying connectivity are left as exercises for the viewer.

Complete lab solutions can be found in the provided link for reference.

Lab Completion Status

The speaker acknowledges that they did not complete all tasks correctly in this preview.

Missing configurations on Router1 and Switch1 are highlighted in red text.

Configuration status of PCs on Switch2 is fine since no additional configurations were required.
