Learning Objectives
- Troubleshoot and correct the Inter-VLAN issues and configuration errors
- Document the network configuration
Introduction
In this activity, you will troubleshoot the network, find and correct all configuration errors, and document the corrected network.
Task 1: Troubleshoot and Correct the Inter-VLAN Issues and Configuration Errors
Begin by identifying what is working and what is not:
What is the state of the interfaces?
What hosts can ping other hosts?
Which hosts can ping the server?
What routes should be in the R1 routing table?
What could prevent a configured network from being installed in the routing table?
When all errors are corrected, you should be able to ping the remote server from any PC or any switch. In addition, you should be able to ping between the three PCs and ping the management interfaces on switches from any PC.
Task 2: Document the Network Configuration
When you have successfully completed your troubleshooting, capture the output of the router and all three switches with the show run command and save it to a text file.
