EIGRP Troubleshooting Sim
Question
Refer to the topology. Your company has connected the routers R1, R2 and R3 with serial links. R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also connected to the routers R4 and R5.
The EIGRP routing protocol is configured. You are required to troubleshoot and resolve the EIGRP issues between the various routers. Use the appropriate show commands to troubleshoot the issues.
Instead of posting the output of “show run” commands we post here the commands entered on each router to reduce some useless lines. Also you can try solving questions by yourself before reading the answers.
| R1: int lo0 ip address 10.1.1.1 255.255.255.255 int e0/0 ip address 192.168.16.1 255.255.255.0 int s1/1 ip address 192.168.13.1 255.255.255.0 bandwidth 1000 int s1/3 ip address 192.168.12.1 255.255.255.0 ! router eigrp 1 network 192.168.12.0 network 192.168.13.0 network 192.168.16.0 |

Note: In the exam, this sim uses IOS version 15 so “no auto-summary” is the default setting of EIGRP. You don’t have to type it.

Question 1
The loopback interfaces on R4 with the IP addresses of 10.4.4.4/32, 10.4.4.5/32 and 10.4.4.6/32 are not appearing in the routing table of R5. Why are the interfaces missing?
A. The interfaces are shutdown, so they are not being advertised.
B. R4 has been incorrectly configured to be in another AS, so it does not peer with R5.
C. Automatic summarization is enabled, so only the 10.0.0.0 network is displayed.
D. The loopback addresses haven’t been advertised, and the network command is missing on R4.
Answer: B
Explanation
On R4 we see EIGRP is configured with AS 2 (router eigrp 2) while other routers are using AS 1 (router eigrp 1). Therefore R4 cannot see other routers and vice versa.
Question 2
Which path does traffic take from R1 to R5?
A. The traffic goes through R2.
B. The traffic goes through R3.
C. The traffic is equally load-balanced over R2 and R3.
D. The traffic is unequally load-balanced over R2 and R3.
Answer: A
Explanation
For this question we have to check the routing table of R1 to find out the answer. Use the “show ip route” command on R1 we will get something like this:
There are three interfaces on R5 which are Loopback0: 10.5.5.5 ; Loopback1: 10.5.5.55; Ethernet0/0: 192.168.123.5 and all of them are advertised via 192.168.12.2 so we can conclude traffic from R1 to R5 goes through R2 (192.168.12.2 is the IP address of S2/1 interface of R2).
Note: Maybe there is another version of this question in the exam in which the answer should be “The traffic is equally load-balanced over R2 and R3″. Therefore please check the “show ip route” output carefully to see if there are more than one route to the destination.
Question 3
Router R6 does not form an EIGRP neighbor relationship correctly with router R1. What is the cause for this misconfiguration?
A. The K values mismatch.
B. The AS does not match.
C. The network command is missing.
D. The passive-interface command is enabled.
Answer: C
Explanation
From the configuration of R6 we learn that R6 is missing “network 192.168.16.0″ command (the network between R1 & R6) under EIGRP so EIGRP neighbor relationship will not be formed between them.
Question 4
Study the following output taken on R1:
| R1#ping 10.5.5.55 source 10.1.1.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.5.5.55, timeout is 2 seconds: Packet sent with a source address of 10.1.1.1 . . . . . Success rate is 0 percent (0/5) |
Why are the pings failing?
A. The network statement is missing on R5.
B. The loopback interface is shut down on R5.
C. The network statement is missing on R1.
D. The IP address that is configured on the Lo1 interface on R5 is incorrect.
Answer: C
Explanation
R1 does not advertise its loopback 0 (10.1.1.1) to EIGRP therefore a ping to destination 10.5.5.55 (R5) from 10.1.1.1 will not be successful because R5 does not know how to reply to R1.

Hey everyone…I just Passed my CCNA composite exam two days ago. I was scared as hell but once I sat for the exam, everything started to become smooth as water. I was really amazed to see that the question were exactly the same as 9tut. Even the options are same. Not only I PASSED, i GOT 1000/1000. Credit goes to 9tut. Without you guys, it would have been impossible. So those of you who wants to sit for the exam just do this 3 things to prepare.
1) Finish all the questions available in 9tut.( Dont just do them, understand them and do them
2) Finish some latest dumps such as Watson
3) Try to practice all types of lab but certainly practice and learn ACL1, ACL2 and EIGRP.
If this 3 things are done properly, be sure that you will get 1000/1000. (email me only if you really need more help) Thank you.
sanamchowdury007 >> did u get error message “this command is not supported in this version “when u typing command on the Qlab if u know it can u tell me what can i do when i find somthing like this error
sanamchowdury007 >> did u get error message “this command is not supported in this version “when u typing command on the Qlab if u know it can u tell me what can i do when i find somthing like this error message
Yes Osman..I found many commands which showed this message. But you dont have to worry because the commands which are required to complete the lab will sure be executable. Even help and tab buttons works in the lab so no reason to worry. Just practice everything from 9tut and get ready…Cheers
okkk thanks sanam now i can take the exam in this week thank u so match u ar so kind my regards
when i use the eigrb lab i just change the AS to the right AS in exam no somthing more ?? is that all in eigrb lab exam ??
I am planning to do my ccna certification in June.. I read here different posts about acl1 and acl 2. where can i find these? also i se lots of labs here about EGIRP and ospf and so on.. do you guys study all these??
I really appreciate your help. I am in toronto… here is my email if anyone is kind enough to help guiding me here.
torontoman66@gmail.com
Osman….You ncannto just change the AS number. You will have to put the no command on the wrong AS. Then you will have to create a new AS and put the right network commands. Please refer to the 9tuts EIGRP 212 section for better detailed solution. You should grasp everything in detail from there. Thanks
And on this lab, you wont have to write any command. You will just have to see the configuration and find out whats wrong according to the question.
no no just practice 3 labs eigrb, acl,acl2 these are just inside the exam
guys if i found passive-interface in the router eigrb what can i do ..؟؟
you must use command “no passive-interface” on interface of router.
their is some discount going on in ccna exam fee this news is correct or fake can any one tell me about that
@Akshay..yeah that news is correct..20% discount is going on n it will be til 31st May..
Hello guys, may I have last dumps please? af84consulting@gmail.com
I need acl1 and acl2 too, where I can find it?
Thanks!
Hi guys.i m confuse with Q4.when i ping 10.5.5.55 from R1.it shows me “percent (5/5).and i know this R5 had advertised its network..i think we need to ping 10.1.1.1 from R5.then it will show us “percent (0/5).
Hello, those who passed exam, can you say which dumps are valid and which variety of simulations are there?
And if someone good want to share a valid latest or not-latest dump i am very thankful house.md.88@hotmail.com Thanks
