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.

DMVPN_BGP.jpg

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).

    Thanks for all above comments and reviews!!!

    I have passed my CCIE 400-101 LAB test on 14/Aug/2018 from Brussels.

    The exam is not easy, a little difficult in fact.

    I practiced that premium PassLeader 400-101 LAB study materials for several times, which helped much for my passing!!!

    And, I highly recommend those who are preparing for the CCIE LAB test to try that premium PassLeader 400-101 LAB study materials, not very expensive, but really helpful.

    Good luck, all!!!

    Congratulations!!!

    Just passed the CCIE R&S 400-101 LAB yesterday (21/Aug/2018, Beijing)~~~LOL~~~

    I got the TS2 and D3 and H2+.

    In the TS2 section, there is no R51 in the OSPF of R60, DO NOT CARE THE R51. And, pay attention to route-map of R11 and R20 (DC2 10.4).

    And, that premium PassLeader 400-101 LAB dumps (or study materials) are still valid enough for passing, it helped a lot for my passing!!!

    Good luck, all! Wish you pass the CCIE R&S LAB!!!

    I just passed the CCIE exam last week. I bought the topic here. The topic is true and effective. I have practiced most of the exam questions, but you have to remember the answer. You can’t just remember it. The options, I have encountered several questions in it, the options for the correct answer have been changed.

    3. between sw1 and sw3

    Q2. Hacker Attack
    1. tcp, sniffer packet –> Attacker and Victim
    2. sudo shutdown
    3. tclsh Victim

    H3:
    Same as the premium PassLeader 400-101 LAB dumps (or, study materials).

    Thanks those who share their exam passing tips and thanks valid PassLeader 400-101 LAB dumps (study materials).

    Congrats!!!

    Passed the CCIE R&S 400-101 LAB few days ago! (7/Mar/2019, Dubai, UAE)

    I mainly used the premium PassLeader 400-101 LAB Dumps collection.

    Here are some tips from my actual test FYI:

    TS2:
    Q1: access no 10 no 30, DHCP no lease 0 2 0
    Q2: SW111-port cost-9, R12-0.0.0.0-cost-31/30
    Q3: R23-lo0; R22-route map-set metric
    Q4: R20/21-local pre-route map
    Q5: R60-tun0-mask
    Q6: R100-e0/0-no ip add dhcp

    DIAG 2:
    Same as the premium PassLeader 400-101 LAB Dumps collection.

    H3:
    1. VTP mode off is available, do not care it
    2. Pay attention to mode access
    3. SW300/SW301-no span mst sim pvst global-old problems
    4. Four AS65001-one of them has LO 2000-OSPF, R13-add ipv4-bgp additional path select best 2-I didn’t do it, it all depends on the IOS
    5. Section 2.6-I used show run | se router-id
    6. AS65002-Next Hop-ATTENTION!!!
    7. AS10000-IP-not 100.0.0.3-is 100.3.3.3, then is 100.4.4.4…etc.
    8. LAN TO LAN IPSEC-ping 8.8.8.8

    That’s all.

    All in all, all TS and DIAG and LAB Config questions are from the premium PassLeader 400-101 LAB Dumps collection, only some small TSET Circumstances are not same, which are less important.

    I highly recommend you to try the premium PassLeader 400-101 LAB Dumps collection!

    Hi guys

    I successfully passed the exam with PH’s dumps!

    Q1: Layer 2(2 point):
    PC101 should successfully access Server 1 behind SW1.
    PC101 cannot access R7/R8, fix the problem so that PC101 can access server1, R7 R8

    Q2: PPP(2 point)
    R17 should have one default route which points to R12 via PPP and R11 should have access via telnet to R17 as shown below.

    Q3: OSPF(2 point)
    When R1 tries to access the network 123.45.67.48/29, which is between R21 and R22, the traffic should be load balanced as shown in the exhibit.

    Cisco will change in 2020, the guys who want to take the exam should hurry.

    So go to the exam as soon as possible!

    Good luck!
