TroubleShooting Lab Challenge 3

July 23rd, 2016 in Lab Challenge Go to comments

This lab challenge helps you understand more about DMVPN. Below is the topology for this challenge.


Description about this lab challenge:

+ R1 is working as the DMVPN Hub router while R7 & R8 are working as DMVPN Spokes
+ EIGRP AS 100 is running from R2 to R6
+ R2 to R6 are running BGP AS 65002 while R1 is running BGP AS 65001
+ All iBGP neighbors use loopback0 to establish BGP neighborship

There are 19 tickets waiting you to resolve. Each of them only contains one error. Please read the description of each ticket to see which spoke cannot communicate with the Hub to have better troubleshooting strategy.

Ticket 1 Ticket 2 Ticket 3 Ticket 4 Ticket 5 Ticket 6 Ticket 7 Ticket 8 Ticket 9 Ticket 10
Ticket 11 Ticket 12 Ticket 13 Ticket 14 Ticket 15 Ticket 16 Ticket 17 Ticket 18 Ticket 19  

Note about NHRP: In some tickets a ping from R7 to R8 (and vice versa) may fail but the NHRP is still working fine on the local router. This is because NHRP only needs to reach the Hub from the local Spoke (while the path from the Hub to the other Spoke may fail). For example, if something goes wrong on R3, NHRP is still working correctly on R8 (although a ping from R8 to R7 fails) because NHRP only needs to go through from R8 to R1 (Hub).

    On February 24, Cisco will have major changes, the exam difficulty will be upgraded, and it will be difficult to obtain a stable dump in a short period of time. It was easy to pass the CCNP and CCIE exams before February, and the dump is very stable. Now is the best time to take the exam. Cisco certifications obtained before the reform are still valid and more valuable.
