CCNA Implementation SIM
This topology contains 3 routers and 1 switch. Complete the topology.
Drag the appropriate device icons to the labeled Device
Drag the appropriate connections to the locations labeled Connections.
Drag the appropriate IP addresses to the locations labeled IP address
(Hint: use the given host addresses and Main router information)
To remove a device or connection, drag it away from the topology.
Use information gathered from the Main router to complete the configuration of any additional routers. No passwords are required to access the Main router. The config terminal command has been disabled for the HQ router. The router does not require any configuration.
Configure each additional router with the following:
Configure the interfaces with the correct IP address and enable the interfaces.
Set the password to allow console access to consolepw
Set the password to allow telnet access to telnetpw
Set the password to allow privilege mode access to privpw
Note: Because routes are not being added to the configurations, you will not be able to ping through the internetwork.
All devices have cable autosensing capabilities disabled.
All hosts are PC’s
Answer and explanation
Note: You can download this sim to practice here: http://www.9tut.com/download/9tut.com_CCNA_Implementation_question.zip
Specify appropriate devices and drag them on the “Device” boxes
For the device at the bottom-right box, we notice that it has 2 interfaces Fa0/2 and Fa0/4; moreover the link connects the PC on the right with the device on the bottom-right is a straight-through link -> it is a switch
The question stated that this topology contains 3 routers and 1 switch -> two other devices are routers
Place them on appropriate locations as following:
(Host D and host E will be automatically added after placing two routers. Click on them to access neighboring routers)
Specify appropriate connections between these devices:
+ The router on the left is connected with the Main router through FastEthernet interfaces: use a crossover cable
+ The router on the right is connected with the Main router through Serial interfaces: use a serial cable
+ The router on the right and the Switch: use a straight-through cable
+ The router on the left and the computer: use a crossover cable
(To remember which type of cable you should use, follow these tips:
- To connect two serial interfaces of 2 routers we use serial cable
– To specify when we use crossover cable or straight-through cable, we should remember:
Group 1: Router, Host, Server
Group 2: Hub, Switch
One device in group 1 + One device in group 2: use straight-through cable
Two devices in the same group: use crossover cable
For example: we use straight-through cable to connect switch to router, switch to host, hub to host, hub to server… and we use crossover cable to connect switch to switch, switch to hub, router to router, host to host… )
Assign appropriate IP addresses for interfaces:
From Main router, use show running-config command:
(Notice that you may see different IP addresses in the real CCNA exam, the ones shown above are just used for demonstration)
From the output we learned that the ip address of Fa0/0 interface of the Main router is 192.168.152.177/28. This address belongs to a subnetwork which has:
Increment: 16 (/28 = 255.255.255.240 or 1111 1111.1111 1111.1111 1111.1111 0000)
Network address: 192.168.152.176 (because 176 = 16 * 11 and 176 < 177)
Broadcast address: 192.168.152.191 (because 191 = 176 + 16 – 1)
And we can pick up an ip address from the list that belongs to this subnetwork: 192.168.152.190 and assign it to the Fa0/0 interface the router on the left
Use the same method for interface Serial0/0 with an ip address of 192.168.152.161
Increment: 16
Network address: 192.168.152.160 (because 160 = 16 * 10 and 160 < 161)
Broadcast address: 192.168.152.175 (because 176 = 160 + 16 – 1)
-> and we choose 192.168.152.174 for Serial0/0 interface of the router on the right
Interface Fa0/1 of the router on the left
IP (of the computer on the left) : 192.168.152.129/28
Increment: 16
Network address: 192.168.152.128 (because 128 = 16 * 8 and 128 < 129)
Broadcast address: 192.168.152.143 (because 143 = 128 + 16 – 1)
-> we choose 192.168.152.142 from the list
Interface Fa0/0 of the router on the right
IP (of the computer on the left) : 192.168.152.225/28
Increment: 16
Network address: 192.168.152.224 (because 224 = 16 * 14 and 224 < 225)
Broadcast address: 192.168.152.239 (because 239 = 224 + 16 – 1)
-> we choose 192.168.152.238 from the list
Let’s have a look at the picture below to summarize
Configure two routers on the left and right with these commands:
Router1 = router on the left
Assign appropriate IP addresses to Fa0/0 & Fa0/1 interfaces:
Router1>enable
Router1#configure terminal
Router1(config)#interface fa0/0
Router1(config-if)#ip address 192.168.152.190 255.255.255.240
Router1(config-if)#no shutdown
Router1(config-if)#interface fa0/1
Router1(config-if)#ip address 192.168.152.142 255.255.255.240
Router1(config-if)#no shutdown
Set passwords (configure on two routers)
+ Console password:
Router1(config-if)#exit
Router1(config)#line console 0
Router1(config-line)#password consolepw
Router1(config-line)#login
Router1(config-line)#exit
+ Telnet password:
Router1(config)#line vty 0 4
Router1(config-line)#password telnetpw
Router1(config-line)#login
Router1(config-line)#exit
+ Privilege mode password:
Router1(config)#enable password privpw
Save the configuration:
Router1(config)#exit
Router1#copy running-config startup-config
Configure IP addresses of Router2 (router on the right)
Router2>enable
Router2#configure terminal
Router2(config)#interface fa0/0
Router2(config-if)#ip address 192.168.152.238 255.255.255.240
Router2(config-if)#no shutdown
Router2(config-if)#interface serial0/0
Router2(config-if)#ip address 192.168.152.174 255.255.255.240
Router2(config-if)#no shutdown
and set console, telnet and privilege mode passwords for Router2 as we did for Router1, remember to save the configuration when you finished

pls send me last question…………………….nikunj_ec09@yahoo.com
@9 tut I am confused with configuring password there its given:
+ Console password:
Router1(config-if)#exit
Router1(config)#line console 0
Router1(config-line)#password consolepw
Router1(config-line)#login
Router1(config-line)#exit
+ Telnet password:
Router1(config)#line vty 0 4
Router1(config-line)#password telnetpw
Router1(config-line)#login
Router1(config-line)#exit
But in ICND1 Book its given:
for console line:
line console 0
login
password………….
for telnet:
line vty 0 15
login
password……….
why the value of vty is taken 5?
9 TUT COULD U EXPLAIN IT.
@RanjeetaL It depends on the number of vty line on that device. To learn that number just type “line vty ?”
“line vty 0 4″ means that 5 connections (users) can telnet to that device simultaneously.
“line vty 0 15″ means that 16 connections (users) can telnet to that device simultaneously.
Are these simulations enough for my ccna exam???
i am givin my ccna exam on 16th aug, if any body has the latest dumps please mail me at rashant_7@yahoo.com….
@ 9 TUT
THX….. COULD YOU EXPLAIN ME REGARDING TO PASSWORD CONFIGURATION
i finally can say the words “got certified today”.
was acl, vtp and eigrp sims. formats in display here on 9tut. study them properly and u’d be there.
read up enough dumps. helps too. all d best people and thanx to 9tut.
pls does 9tut have any idea of a site like this one for CCNP assistance?
@mobi: We have http://www.digitaltut.com for ROUTE, http://www.certprepare.com for SWITCH & http://www.networktut.com for TSHOOT.
Can any body will tell me as i have gone through all the literature mentioned in this site for the CCNA prepration I want to give the test in the next week without reading any other material can i pass the exam easily
awesome work 9tut, my doubts are crystal clear:)
In exam…. is this question like packet tracer simulation work…? or different pls explain….?
To Honey, no if you don’t know how to do this stuff and rely on just this than you are not going to pass it.
what are the major topics that we have to cover mostly in CCNA……?
wich simulation s will come most of the time??? pls share frnds…
thanks & regards,
Ganesh
@9tut
i can also assign 192.168.152.177 instead of 192.168.152.190 to the interface fa0/0 of router to the left. still it is in the same subnet. i used the first usable address instead of the last usable address.
i can also assign 192.168.152.161 instead of 192.168.152.174 to the interface of s0/0 of router to right. still it is in the same subnet. i used the first usable address instead of the last usable address.
correct me on that.
Are these simulations enough for my ccna exam?
i am givin my ccna exam on 21th oct, if any body has the latest dumps please mail me at musa_gacemer@windowslive.com
pls share frnds
@manila
yes .177 and .190 were on the same subnet but you can’t use that on int fa 0/0 of router 1 because .177 is already assigned to int fa 0/0 of main router, you can issue the show run syntax on the main router to verify.
…. same case with the router on the right side.
the simulation is causing confusion.
view the show run output from main in the simulation, and it is wrongly assigned the ip addresses : .178 (fa0/0) and .172 (s0/0)..instead of the .177 and .161 which would’ve eliminated both of these answers as possible answers (per Manila’s & jrm’s comment).
if the Main was indeed assigned .177 and .161, then the right answers are obvious.
request to 9tut to please correct the sim configuration..and ofcourse great site, thanks 9tut for everything.
@happycamper: Yes, thanks for your detection. I updated the sim.
hello 9 tut
we can use
192.168.152.177/28 instead of 192.168.152.190
for Router1 fastethernet interface
cos the two Ip address are same subnet.
that is right?
@pp: We can’t use 192.168.152.177 because interface fa0/0 of the Main router has used it.
Ips in the sim differs from the demonstration pic ,,, so answers not valid
I did the CCNA test on Wednesday and passed it with 881. This web is very helpful. Thank you all
how can download this lab simulations and attempt them like a realtime eaxam
Pls how can download this lab simulations and attempt them like a realtime exam. Can someone respond immediately @ alvinlannie@yahoo.com
With this cheat sheet you can easily solve any subnetting assignment without using any math. Most questions solved in matter of seconds.
http://quest4.org/ccna/subnet_cheat_sheet.htm
There’s a guide regarding how to use it as well.
Hope you like it!
May the Dumps is valid that is 486 till now.
ip address assin to pc
Do we need to put that line “transport input telnet” after setting the telnet password?
@ CHarles—-> NO.
Wat is the passing marks for CCNA Certification…??
passing marks for CCNA is825
@9tut
pls how do you come by the choice of ip for A and C hosts, couldn`t you have given any of the two remaining ips to any of the hosts?
Router1(config-if)#ip address 192.168.152.142 255.255.255.240
Router2(config-if)#ip address 192.168.152.238 255.255.255.240
i don,t understand why these address are given to f0/1 and f0/0 please tell me
@rashid: Because the other end of the interface should fall in the same subnetwork.
In this case, 192.168.152.142 falls in “192.168.152.128 – 192.168.152.143″ so does 192.168.152.129.
And 192.168.152.238 falls in “192.168.152.224 – 192.168.152.239″ as well as 192.168.152.225.
Subnetting simply! (i.e. multiples of 16 in this example)
would like to know if this is included in the exam?
@panyang: Of course! the stuff you will find on this web site will certainly help you get through the exam, but the matter of fact is you should grasp this information too!
actualtest.com dumps are valid or not plz tell me?
there is some confusi0n here.router fa 0/0 interface connected t0 the main r0uter has ip .178 ,not 177 ,s0 for fa 0/0 we have 2 ip 0pti0ns which are .177 & .190.b0th these are valid .can anyone answer this????
same issue with serial ip.show running sh0w that ip on serial link is .172 so we have 161 & 174 option .
Where do I purchase the 9tut virtual ccna study material.
Please send me latest dumps on kstojilkov@yahoo.com
does ‘?’ command work for this simulation question?
I passed ccna to day my score 930 very thanks 9tut.
Ib line vty if the device support 0 15, does it work if you use 0 4 in the real exam??
I want to know why the cisco website is just so hard to understand? Without 9tut these exams would be really hard. I look up things on cisco site to find out that I am even more confused. My teacher really made me study the subnetting. I have that down. Now I need to get the passive interface command down. Wikipedia simplifies its explanations. Who ever the authors are for cisco — they are just plain hard to understand. The cisco course explains a lot to the new person — but 9tut seems to fill in the gaps with practical explanations.
From wikipedia: the topology table is confusing —yes thanks— contains aggregate of routing tables collected from neighbors — plain, clear English — yeah !!!!!
Passive interface — does it work with RIP and OSPF?
use show ip protocols to determine if passive interface
For Router on the left of the Main, I want to know you did not choose the ip address 192.168.152.177 since it also belongs to the subnet 192.168.152.176 – 192.168.152.191 as it seems to be a correct ip address to that Router.
Thank you for your response
Why you did not choose that ip address?
