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 stating that following some configuration changes, the OSPF neighbor adjacency between R1 and R2 has failed. Troubleshoot and resolve this issue.
Trouble Ticket # 2
You have received a call from Level 1 stating that following some basic network configuration changes, the OSPF adjacency between R2 and R3 is down. Troubleshoot and resolve this issue.
Trouble Ticket # 3
You have received a call from Level 1 stating that the OSPF adjacency between R3 and R4 is down. Troubleshoot and resolve this issue.
Trouble Ticket # 4
You have received a call from Level 1 stating that there is intermittent connectivity between the 150.1.1.0/24 and 150.2.2.0/24 subnets and the 150.4.4.0/24 subnet. Due to a current configuration freeze on R3, Management allows you to only make changes to ONE device. With this restriction in mind, troubleshoot and resolve this issue.
