Introduction

This week’s lab activity focuses on the configuration of inter-VLAN routing to facilitate communication between hosts in different VLANs. It also demonstrates router-on-a-stick and multilayer switching to ensure that devices in different VLANs are able to communicate.

Procedure

• I configured a dot1q trunk link between the Core Switch and the Edge router

• Configured sub-interfaces on the Edge router to map VLANs to the router interface

• Verified configuration to prove that the Edge router NYEDGE1 could be used to route between VLANs using a single physical interface

Results

After configuration was complete, I used some show commands to verify the trunk link and Inter-VLAN routing was working correctly

• Show ip interface brief: displays a list of interfaces with their IP address details and link status

• Show interfaces trunk: displays trunk interfaces configured with the allowed VLANS

• Show vlan: displays list of configured vlans with associated switchports

• Show run | s router ospf :skims the running config for lines matching the keyword

Application and Analysis

This Lab was great, I was able to run debug commands and learn how to configure and verify VLANs, Trunking and Inter-VLAN routing

Questions

1. What new concepts or theories have you learned about after completing this lab activity?

I learned how to troubleshoot, L2 and L3 problems in a multi-vlan LAN network

2. In this class, we use the three steps approach to complete the lab activity. The steps include plan, implement, and verify. Discuss and explain how you execute each step in this lab activity.

PLAN: Examine network diagram, read through design objectives weigh merits of design options

IMPLEMENT: Configure routers based on chosen design option inline with the requirements and objectives of the LAB

VERIFY; Use show commands to ensure design requirements are met

3. What challenges, if any, have you encountered in this lab? How have you addressed those challenges? If you have not experienced any challenge, tell us what new troubleshooting commands you have learned this week and how that command has helped you complete the lab activity.

• Show ip interface brief: displays a list of interfaces with their IP address details and link status

• Show interfaces trunk: displays trunk interfaces configured with the allowed VLANS

• Show vlan: displays list of configured vlans with associated switchports

• Show run | s router ospf :skims the running config for lines matching the keyword

Lessons Learned

LAB provided the basic knowledge required to configure and verify trunking, Inter-VLAN routing an d

Router-on-a-stick for given network requirements
