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

Your co-worker has advised that after some configuration changes were made, they are now no longer able to reach any devices on the 3FFE:1111:1111:1111::/64 subnet from R2. Troubleshoot and resolve this issue.

Trouble Ticket # 2

Your co-worker has completed configuring MP-BGP on R2 and R3; however, they are unable to get the adjacency to be established. Troubleshoot and resolve this issue.

Trouble Ticket # 3

You have received a problem report that Level 1 is unable to reach the 3FFE:1111:1111:1111::/64 subnet from R3. Troubleshoot and resolve this issue.
