CCNA Configuration SIM Question
Question:
To configure the router (R2-RC) click on the console host icon that is connected to a router by a serial console cable (shown in the diagram as a dashed black line)
CCNA Training Company recently installed a new router in their office. Complete the network installation by performing the initial router configurations and configuring RIPV2 routing using the router command line interface (CLI) on the R2-RC.
Name of the router is R2-RC
Enable-secret password is cisco1
The password to access user EXEC mode using the console is cisco2
The password to allow telnet access to the router is cisco3
IPV4 addresses must be configured as follows:
Ethernet network 209.165.202.128/27 – router has last assignable host address in subnet
Serial network is 192.0.2.16/28 – router has last assignable host address in the subnet. Interfaces should be enabled.
Router protocol is RIP V2
| Attention : In practical examinations, please note the following, the actual information will prevail. 1. Name of the router is xxx 2. Enable-secret password is xxx 3. Password to access user EXEC mode using the console is xxx 4. The password to allow telnet access to the router is xxx 5. IP information |
Solution
(Note: If you are not sure how RIP works, please read my RIP tutorial: http://www.9tut.com/rip-routing-protocol-tutorial. Note: You can download this sim to practice here: http://www.9tut.com/download/9tut.com_CCNA_RIP_Configuration.zip)
1) Name the router:
Router>enable
Router#configure terminal
Router(config)#hostname R2-RC
2) Set secret password:
R2-RC(config)# enable secret cisco1
3) Set password for the console:
R2-RC(config)#line console 0
R2-RC(config-line)#password cisco2
R2-RC(config-line)#login
R2-RC(config-line)#exit
4) Set the Telnet password:
R2-RC(config)#line vty 0 4
R2-RC(config-line)#password cisco3
R2-RC(config-line)#login
R2-RC(config-line)#exit
5) Assign IP address for Ethernet interface (Fa0/0):
The Ethernet network 209.165.202.128/27 has:
Increment:32 (/27 = 255.255.255.224 or 1111 1111.1111 1111.1111 1111.1110 0000)
Network address: 209.165.202.128
Broadcast address: 209.165.202.159 (because 128 + 32 – 1 = 159)
Therefore the last assignable host address in this subnet is 209.165.202.158 and we will assign it to Fa0/0 interface with these commands:
R2-RC(config)# interface fa0/0
R2-RC(config-if)#ip address 209.165.202.158 255.255.255.224
R2-RC(config-if)#no shutdown
R2-RC(config-if)#exit
6) Assign IP address for Serial interface (S0/0/0):
Serial network 192.0.2.16/28 has:
Increment:16 (/28 = 255.255.255.240 or 1111 1111.1111 1111.1111 1111.1111 0000)
Network address: 192.0.2.16
Broadcast address: 192.0.2.31 (because 16 + 16 – 1 = 31)
So the last assignable host address in this subnet is 192.0.2.30. Finally we assign it to s0/0/0 interface:
R2-RC(config)# interface s0/0/0
R2-RC(config-if)#ip address 192.0.2.30 255.255.255.240
R2-RC(config-if)#no shutdown
R2-RC(config-if)#exit
7) Configure RIP v2 routing protocol:
R2-RC(config)#router rip
R2-RC(config-router)#version 2
R2-RC(config-router)#network 209.165.202.0
R2-RC(config-router)#network 192.0.2.0
R2-RC(config-router)#end
R2-RC#copy running-config startup-config
Note: We should use classful networks (209.165.202.0 & 192.0.2.0) when configuring RIP. If we use detailed networks (209.165.202.128 & 192.0.2.16) the router will automatically convert them into classful networks.
please i need your helping for ccna exam coz of i do not know any thing about configuration quation i got confuseing
hi guys…
Can somebody please explain when do we use no auto-summary and when do we don’t use it ?
@9tut
sir: serial interface used clcok rate
How could anyone say that with these two networks, this address scheme is not discountigous?
network 209.165.202.128
network 192.0.2.16
Wouldn’t RIPv2 need the “no auto-summarization” command, so it does not summarize to classful boundary?
Why enter these networks?
209.165.202.0
192.0.2.0
Their CIDRs indicate they start with sub-nets 128/27 and 16/28; so why start them with 0 rather than 209.165.202.128/27 192.0.2.16/28?
Can somebody please explain when do we use no auto-summary and when do we don’t use it ?
sh ip routein R2-RC
only
c 209.165.202.0
wo is the Network of serial ist too diricktly connected please help me Thanks
@Fawzi: You can learn about “no auto-summary” here (at the end of this article): http://www.9tut.com/eigrp-routing-protocol-tutorial/3
why u didn’t add “no auto-summary” command ??
@acl
It’s not a discontiguous network so you don’t need it. However, in practice you probably want to always put it in. Would be nice if it was on by default.
Hi guys,
Just one comment, the two line below are wrong for the exam, we shouldn’t write the all IP address just the network address. In real world it would work but for the exam it will to lose some point, I read it from Todd Lammle book.
Wrong:
R2-RC(config-router)#network 209.165.202.128
R2-RC(config-router)#network 192.0.2.16
Correct:
R2-RC(config-router)#network 209.165.202.0
R2-RC(config-router)#network 192.0.2.0
@9tut
Should we also configure router R1/RT? (so we can verify that rip is correctly configured)
Thanks
@maja: In the exam we are only allowed to configure R2-RC.
@Aerodesliza: The router will automatically convert them into classful networks. I updated the “network” statements so that no one will be confused in the future.
Check if the protocol is up or down from old router ‘show ip interface brief’, if it’s down and clock rate is not set, do it then the topology shall be converged.
@jandro https://learningnetwork.cisco.com/thread/10419
Hi, taking into account that I cannot configure R1-RT router I shall configure clock rate on the R2-RC router (if the serial link between these 2 routers is down). Am I correct? Thx for reply
Hello all, i am going to take CCNA 640-802 on 10/march/2012 any one please help me how to face and send me last dumps my email nujtxeeg@gmail.com
For the sake of packet tracer results working:
1) you also have enable RIPv2 on the router R1-RT.
2) set clock rate to router R1-RT to Serial 0/0/1, I used clock rate 6400 as an example
From what I can read in the actual exam the other router is pre-configured.
I have downloaded sim, but i couldn’t open it with pavket tracer 5.0, How can I open it?
Passed CCNA today with 920, I had ACL2,VTP and EIGRP, it was a bit nerve racking but revising paid off.
Many thanks 9tut but more importantly thank GOD.
I shall be making a donation to 9tut.
if you can not ping the neighbour routers ip set the clock rate on both routers serial interfaces
To set Clock rate on Router’s Serial Interface
router>enable
router#configure terminal
router(config)#interface s0/0
router(config-if)#clock rate 64000
Yerla
if works fine on version 5.3
In this lab it is still best to use no auto-summary because it can’t be marked wrong. Plus you should get in the habit of using the no auto-summary command anyways.
Hi Guys i will write the ccna excamination next week , so kindly send me latest ccna dumps . it would be very big helpful for me . i never forget your help . please….. this is my mail id “mageshkumar710@gmail.com”.
Line Protocol is down… clock rate is not set on the adjacent serial interface…. and NO Auto-summary is not required here b/c its not discontiguous….. but there is no harm in using it as far as i am concerned

I took the exam yesterday and passed with 867 thanks to 9tut and examcollection. The labs were Eigrp, VTP and Access lists. If I had money I would have donated immediately, you deserve it!
@9tut
I have a question regarding configuring vty lines in the certification exam, like in this SIM for example.
I always use the ? symbol when entering commands and I have notice that most routers and switches support 0 – 15 vty lines rather than 0 – 4 vty lines.
If by any chance, this SIM is part of the certification exam, and by using the ? symbol I determine that the router supports 0 – 15 lines instead of 0 – 4, what would you suggest ?
A. use this configuration
R2-RC(config)#line vty 0 4
R2-RC(config-line)#password cisco3
R2-RC(config-line)#login
R2-RC(config-line)#exit
B. or use this one
R2-RC(config)#line vty 0 15
R2-RC(config-line)#password cisco3
R2-RC(config-line)#login
R2-RC(config-line)#exit
I would like to ask you kindly to clarify this for me. Thanks in advance!!!
@Danilin,
If you use Packet Tracer software to access the routers or switches; you can easily access to them fully, there is no any problem for vty 0 4. I have the SIM application ROUTER SIM CCNA NETWORK VISUALIZER 6.0 VERSION but no use of fully access and also had same problem like others routers and switches for vty 0 15 instead of vty 0 4.
So, my suggestion is use PACKET TRACER 5.1 or above version it will work fine.
@Danilin,
One more thing if you are sitting on the exam and it is stated that configure vty 0 4 with passwor xxxxxx, then you have to configure vty 0 4 not vty 0 15. In the exam you will able to access vty 0 4.
@Thapa
Thanks for the response. But what if in the certification doesn’t explicitly say to configure vty lines 0 4 and the device supports 0 15 lines ?
@Danilin
This is the problem occurs on downloaded certification’s simulation, I will recommend to you that keep in mind and follow the principle that you are using vty 0 4 instead vty 0 15. I mean just imagine vty 0 4 instead vty 0 15 but the principal is same. Just follow it. I need to say one more thing…….. I think while configuring VLAN and VTP on that your certification simulation; it won’t support trunking also, because i had the same problem while configuring vtp trunk it does not support too…………………….
Anyway @Danilin do not worry, just download this all whatever simulation over here in the 9tut and practise on them. They are pretty enough for the CCNA exam. I took my exam on 16 May and scored 96%, if you need any help just ping me on ……………….
thapa_ud2008@yahoo.com
I will help to you fully for the CCNA.
@9tut
Thanks for the great work.
Can you please tell me what you mean by – the actual information will prevail? does this mean that the information will be the same in the exam?
Thanks
rangoos
can we use ‘?” for getting help with cisco IOS …
What is the probability that this sim will appear in the exam?
I LOVE U ALL
hi guys
I confuse about this Sentence “To configure the router (R2-RC) click on the console host icon that is connected to a router by a serial console cable”
is that mean I can access the router by the console host?
plz help
@ Anonymous
Yes you can access the Router CLI by clicking on Console host
@ cccccc & Narendra
For some reason my show ip route doesn’t show the rip IP addresses.
I did exactly the same as the solution and even tried the answer packet but not getting the correct result in routing table:

@anish
go to router R1-RT and set the clock rate on interface s0/0/1. that should bring the link up.
i think in the exam u should use the sh controllers (interface) cmd to find out which interface provides the clocking (DCE).
@bblaze
yes…I did it…and I got the networks…..but ping is not working properly…..should we do rip on R1-RT?
@anish
yes u right… to get ping throughout the network you have to have routing configured on R1-RT as well.
hi wazz up
ccna alway jocking hahah
I’ve taken this sim 4 times and cannot get “ip show route” to show up as RIP.
I’ve set up the network correctly with the correct addresses, but no luck at all.
Can anyone help???
Hi, MSP!
You are wrong in the syntax of command, right command is “show ip route” )))
Good luck!
please why don’t we have to put “no auto-summary” in this configuration?
please, can someone help me?
