Packet Tracer 4.0 Troubleshooting Activity: SBA 5S1A-1_D Troubleshooting Inter-VLAN Routing

Objective

Use Packet Tracer to practice and develop the following skills:

Troubleshoot connectivity between VLANs

Verify trunking and Inter-VLAN routing functionality

Scenario

The network topology above represents a simple network that requires a router for communicationbetween VLANs and for examining Inter-VLAN routing functionality. You are given a Class Cnetwork address of 192.168.1.0 with a subnet mask of 255.255.255.224 (or 192.168.1.0 / 27). Thethree subnets starting with Subnet 1, are assigned to each VLAN.

Required Files

To complete this lab, you will need the following file:

SBA5S1A-1_D.pka

Step 1 Open the Required File

1. Start Packet Tracer 4.0

2. Click on File > Open

3. Navigate to the correct directory/folder and open: SBA5S1A-1_D.pka

The following network topology and activity instructions should be displayed:

Step 2 Check Connectivity and Gather Information

1. Using the Packet Tracer Simple or Complex PDU feature in the Simulation mode, ping betweenthe PCs in each VLAN, observe the packets, check the PDU info, and record the results.

Attempt each ping twice.

a. Ping between PC0 and PC1:

b. Ping between PC0 and PC2:

c. Ping between PC1 and PC2:

2. Using the Packet Tracer Inspection Tool or router CLI feature, examine the routing table of therouter.

a. What networks/subnetworks are in the routing table?

1)

2)

3)

3. Examine the router configuration and record the IP addresses and interfaces to which they areassigned.

a.

b.

c.

4. Using the Packet Tracer switch CLI feature, examine the switch configuration.

a. Besides the default VLANs, what other VLANs are configured?

1)

2)

3)

b. What ports are assigned to each VLAN?

1)

2)

3)

4)

5. Using the Packet Tracer PC Config or Desktop features, check the network settings for each PCand record.

a. PC0:

1) IP Address and Subnet Mask:

2) Default Gateway:

b. PC1:

1) IP Address and Subnet Mask:

2) Default Gateway:

c. PC2:

1) IP Address and Subnet Mask:

2) Default Gateway:

Step 3 Examine and Analyze Information Collected and Identify Problem

1. Examine and analyze the information collected in the previous step. Briefly explain your findingsand identify possible causes for the lack of connectivity between one VLAN and the other two.

Step 4 Determine a Plan of Action and Correct the Problem

1. Based upon the information collected and your examination and analysis, what course of actionshould be taken to correct the problem?

2. Using the Packet Tracer router CLI feature, make the changes necessary to correct the problem.

Step 5 Verify Trunking and Inter-VLAN Routing

1. Using the Packet Tracer Inspection Tool then CLI, examine the routing table on the router toverify the subnetworks have been installed correctly.

2. In the Packet Tracer Realtime mode, check end-to-end connectivity between the PCs with asimple PDU and a CLI ping between PCs.

Step 6 Examine the Routed Packets

1. In the Packet Tracer Simulation mode, check that only the ICMP event is selected in the EventLists Filter at the bottom of the Simulation Panel.

2. Reset/clear all entries by clicking on the New button in the Scenario section of the Packet Tracerwindow.

3. Using the Simple PDU option, ping between PC0 and PC1, then ping between PC0 and PC2,then ping between PC1 and PC2, the click on the Auto Capture / Play button and observe thepackets in the Event List window and topology.

4. When satisfied with your configuration, click on "Check Results".
