The problem:
- R3 is connected to R2 via L3 MPLS VPN backbone. R3 and R2 are CEs. R1 and R5 are PEs. R4 is a P router.
- R3 can't ping R2's Lo0 from its Lo0.
- Fix the problem. Do not reduce the security level of the current network.

The problem:
• R1 is configured with redundant bidirectional connection between R3 and R4's Lo0. Its like multihome internet connection setup.
• R2 is the preferred path between R3 and R4.
• R1 is using NAT to allow connectivity, exposing R3 as 4.3.12.3 and 4.3.15.3.
• R3 can't reach R4 and vice versa.
• Fix the problem without changing configuration on R2,R4 and R5. Keep the solution redundant.
• Use telnet to check connectivity. You are allowed to configure one static route.

L2 is now in the TS section
14/01/11 14:07 Filed in: troubleshooting
L2 is now in the TS section of the R&S lab: https://learningnetwork.cisco.com/docs/DOC-10859
L2 is in our TS workbook from day one!
L2 is in the TS workbook from day one because the TS workbook was written not just to prepare the students for the TS section of the lab, but also to summarize, test and sharpen the skills of the CCIE R&S students.
Please notice that although the TS section is the first section of the lab, I recommend to practice the TS section after doing technology focused labs and moc labs. You will need all your networking skills to solve the labs in the TS workbook.
Enjoy your studies :)

The problem:
R6 was configured to summarize R3's Lo30,Lo31,Lo32 and Lo33, so R4 would see only one summarized route for them.However, R4 still sees all the routes.
Fix the problem while, making sure R6 sees all R3's routes.
