IMPORTANT NOTE If you are using the www.howtonetwork.net racks, please download and paste the troubleshooting lab configurations. If you are using your own rack or lab, please modify this configuration to reflect the actual interface types, etc, that you have on your devices. Prior to beginning all labs, apply the pre-lab configuration for each individual device. When completing these labs, it is important to resolve the trouble tickets in the order in which they are listed because they build on each other. For example, if you begin with Trouble Ticket # 3, you might not get the expected resolution or result if you have not completed Trouble Ticket # 1 and Trouble Ticket # 2. It is very important to follow the order listed. |
Trouble Ticket # 1
You have received a call from Level 1 support indicating that following some scheduled WAN changes, connectivity from the 150.3.3.0/24 subnet to the 150.1.1.0/24 and 150.2.2.0/24 subnets has been lost. Troubleshoot and resolve this issue.
Trouble Ticket # 2
You have received a call from the NOC indicating that the EIGRP neighbor relationship between R3 and R4 failed following some scheduled routing configuration changes. Troubleshoot and resolve this issue.
Trouble Ticket # 3
You have received call from users connected to the 150.4.4.0/24 subnet advising that every time there is a report of a failed network link, they lose connectivity to the 150.1.1.0/24 and 150.2.2.0/24 subnets. Troubleshoot and resolve this issue.
Trouble Ticket # 4
You have received call from Level 1 support indicating that users connected to the 150.4.4.0/24 subnet cannot connect to a server with the IP address 150.3.3.254. The NOC has also stated that they are unable to ping R3s LAN interface IP address from R4. Troubleshoot and resolve this.
