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:

  • R3 is the DHCP server on V100.
  • R1 was configured to be a backup for the DHCP server on R3. R1 is using object tracking and EEM to do so.
  • However, the solution is not working and even if it was its too slow and unreliable. Fix the problems.
  • Do not use BFD, its not working on dynamips :)

Finished!

The marathon was really a hard one. 800 meters of total accent (2600ft). But, it was worth it! What a great scenery, it was more a tour then a marathon ;)

Now back to R&S/CCIE stuff. I’ll am working on some new entries to the blog. Stay tuned!

3 weeks to go

I know it is a little slow here in this blog. There is a reason! I am busy. The marathon is 3 weeks from now, so in the past few months I was very busy training.

I have lots of ideas for new mini labs and some other stuff. Stay tuned...

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

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 :)

Happy new year!

I wish you all happy new year.

Lately I was busy authoring R&S MOC labs, so I didn’t have time to post here. I am about to finish. Stay tuned for more TS mini labs.
