CCNA EIGRP LAB Question
Question
After adding R3 router, no routing updates are being exchanged between R3 and the new location. All other inter connectivity and Internet access for the existing locations of the company are working properly.
The task is to identify the fault(s) and correct the router configuration to provide full connectivity between the routers.
Access to the router CLI can be gained by clicking on the appropriate host. All passwords on all routers are cisco.
IP addresses are listed in the chart below.
| R1 Fa0/0: 192.168.77.33 S1/0: 198.0.18.6 S0/1: 192.168.60.25 S0/0: 192.168.36.13 |
R2 Fa0/0: 192.168.60.97 Fa0/1: 192.168.60.113 S0/0: 192.168.36.14 |
| R3 Fa0/0: 192.168.77.34 Fa0/1: 192.168.60.65 Fa1/0: 192.168.60.81 |
R4 Fa0/0: 192.168.60.129 Fa0/1: 192.168.60.145 S0/1: 192.168.60.26 |
Answer and explanation
(Note: If you are not sure how EIGRP works, please read my EIGRP tutorial: http://www.9tut.com/eigrp-routing-protocol-tutorial. Note: You can download this sim to practice here: http://www.9tut.com/download/9tut.com_CCNA_EIGRP_sim_question.zip)
We should check the configuration of the new added router first because it does not function properly while others work well. From the command line interface of R3 router, enter the show running-config command
From the output above, we know that this router was wrongly configured with an autonomous number (AS) of 22. When the AS numbers among routers are mismatched, no adjacency is formed.
(You should check the AS numbers on other routers for sure)
To solve this problem, we simply re-configure router R3 with the following commands:
R3>enable (you have to enter cisco as its password here)
R3#configure terminal
R3(config)#no router eigrp 22
R3(config)#router eigrp 212
R3(config-router)#network 192.168.60.0
R3(config-router)#network 192.168.77.0
R3(config-router)#no auto-summary
R3(config-router)#end
R3#copy running-config startup-config
Check R1 router with the show running-config command:
Notice that it is missing a definition to the network R3. Therefore we have to add it so that it can recognize R3 router
R1>enable (you have to enter cisco as its password here)
R1#configure terminal
R1(config)#router eigrp 212
R1(config-router)#network 192.168.77.0
R1(config-router)#end
R1#copy running-config startup-config
Now the whole network will work well. You should check again with ping command from router R3 to other routers!
Modifications:
Maybe in this EIGRP Sim you will see the “passive-interface …” command somewhere in R1 configuration. If the link between R1 to R2; or R1 to R3; or R1 to R4) routers has the “passive interface” then we have to remove it with the “no passive-interface …” command because it prevents EIGRP update from being sent on that interface. But if the “passive interface” is applied to the link between R1 and ISP router like this:
R1:
!
router eigrp 212
passive-interface s1/0
!
then we just leave it. Don’t use the “no passive-interface s1/0″ on R1 because the link between R1 & ISP doesn’t need EIGRP to run on it. A static route from R1 to ISP & “ip default-network” command in R1 are correct so that all the routers (R1, R2, R3, R4) can access the Internet.
(Note: The “ip default-network” command in R1 will advertise the static route of R1 (to go to the Internet) to other routers (R2,R3,R4) so that they can access the Internet too). In the exam you will see these lines in R1 configuration:
!
ip default-network 198.0.18.0
ip route 0.0.0.0 0.0.0.0 198.0.18.5
!
If you want to learn more about “ip default-network” command please read: http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094374.shtml
I read recent comments and realized that you will see the “passive-interface” in the link between R1 & ISP router so just leave it.
Note: Also some readers confuse about if we should use the wildcard masks on the “network” statements under EIGRP process or not. For example should we use:
router eigrp 212
network 192.168.77.0 0.0.0.3
The answer is: we can use wildcard masks or not, it does not matter. Not having a wildcard mask does not make the routes conflicting. The “network …” command in EIGRP (and OSPF, RIP) does not means “advertise this network” but means “If I has interface(s) belongs to this network please turn on EIGRP on that interface. Therefore when you don’t use wildcard mask EIGRP will turn on EIGRP on all interfaces that belongs to the network you specify in the “network …” command.
You should only use wildcard mask on EIGRP if you have 2 or more interfaces that belong to the same major networks but you don’t want to run EIGRP on all of them. For example if your router has 2 interfaces whose IP addresses are 192.168.30.1/28 and 192.168.30.17/28 but you only want to run EIGRP on the first interface, you can type “network 192.168.30.0 0.0.0.15″ under EIGRP process.
Other lab-sims on this site:
CCNA Configuration SIM Question (RIPv2 SIM)
Do we have to remove interface on R1? Some people are saying that R1 has unnecessary interface, and we need to remove it? Can anyone confirm?
Hi Solomon, Please can you confirm about EIGRP simulation, was there passive interface available needed to remove from R1 for other routers?
Also if we need to remove passive interface can we remove directly from R1 or need to get into specific interface like s1/0?
Thanks
Hi All,

2- On ethernet channel (show run of two switches failed to create chanel why?) ——> answer: speed mismatch
3- on SNMP —> answer: Trap
Hello everybody, I’m quite happy , because i passed today with 972 score; thank you 9tut; you’re doing a great job.

ALHAMDULILLAH, today i passed CCNA 200-120 exam, i got EIGRP , ACL sim & ACL2 sim labs. The DNS Server was removed and Public Server was given an IP. All IP’s were changed.In The EIGRP Lab, The routers were named as HUB router and SERVERS router, AS No. on Servers router was misconfigured and Network between HUB and SERVER router was not advertised on HUB router. I tested the functionality by Pinging the ISP router and saved all the labs before clicking NEXT. There were 51 Qs. my score is 972/1000. The Dumps of 316 Qs. were really helpful.
passed composite 200-120 on 10-feb-2015 as well!
Thanks 9tut!
The terminal i am working at does not allow 1 to write mem nor save configurations. Once you are done, simply click next.
3 lab qns (eigrp, acl mod1, acl – multiple choice, same as 9tut ans)
Eigrp changed router name to mgp, egp and etc. From router eigrp 22 to 12 And add network statement on main mgp router
Acl mod1 – allow host b to access finance web, all other hosts blocked to finance but allowed on private web server
Passed exam 945/1000
valid dump!
ACL1, ACL2, EIRGP
Thanks alot 9tut!
First of all, thanks a lot 9tut. The questions are valid, complete and up to date.
The breakdown of new questions (syslog, netflow,etherchannel etc) was not minimal, so pay attention.
The lab questions were usual, EIGRP lab (with AS 12/22 and only R1 and R3 to be configured), ACL and ACL2 modification 4. I used permit ip any any at the last line and unoffically got the full score.
Hi there,
I passed my exam today. 1000/1000
There were 51 questions including the 3 labs. Everything, all the questions are here. I also used Matthew and Watson. After getting those exams and of course this website nailed down it was really easy to pass. They changed the order of the answers but as I said it wasn’t a problem. I knew because of the comments here that I would find questions from Syslog, HSRP VRRP GLBP, NetFlow and SNMP. The first 5 parts of this website. But even with that, very easy, seriously (if you study of course)
My labs were:
EIGRP. The name of the router was ENG and it was exactly the same as the one here, I mean, to change the area, which was 112.
ACL. Exactly the same as here. 4 questions and you can’t configure anything in the router.
ACL2 modification 1. Computer B can access web browser in Finance Server but nothing else. The rest of the computers can access the Public Server and I wrote “access list 100 permit ip any any” The only thing I couldnt do is to ping the server. The only option was the web browser when I clicked on the computers.
IMPORTANT: I checked all the computers to make sure that the access list worked.
Good luck. Thanks 9TUT. I’m going to have a glass of wine to celebrate. Cheers
Alhamdulilahi, i pass my ccna exam today, the dumps are really valid and the labs are ACLs and EIGRP. 9tut doing a great job. 903/1000
Passed today with 1000/1000 ACL, ACL2 and EIGRP Labs. 2 New Q. Watson, Matthew, Examtut and GillBeast are valid.
I have my exam tomorrow. Any last minute advice? :)
what are the new questions ?????
