RIPv2 SIM
Question:
Central Florida Widgets recently installed a new router in their Apopka office. Complete the network installation by performing the initial router configurations and configuring RIPv2 routing using the router command line interface (CLI) on the Apopka router.
Configure the router per the following requirements:
Name of the router is Apopka
Enable-secret password is cisco10
The password to access user EXEC mode using the console is RouterPass
The password to allow telnet access to the router is scan90
IPv4 addresses must be configured as follows:
Ethernet network 209.165.201.0/27 – router has second assignable host address in subnet.
Serial network is 192.0.2.128/28 – router has last assignable host address in the subnet. Interfaces should be enabled.
Routing protocol is RIPv2.
(Notice: In the real exam the name, passwords, IP addresses and the positions of the assignable host addresses might be different)
Instruction:
To configure the router (Apopka) 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).
Each of the windows can be minimized by clicking on the [-]. You can also reposition a window by dragging it by the title bar.
The “Tab” key and most commands that use the “Control” or “Escape” keys are not supported and are not necessary to complete this simulation. The help command does not display all commands of the help system.
Answer and Explanation:
1) Name the router:
Router>enable
Router#config terminal
Router(config)#hostname Apopka
2) Enable-secret password (cisco10):
Apopka(config)#enable secret cisco10
3) Set the console password to RouterPass:
Apopka(config)#line console 0
Apopka(config-line)#password RouterPass
Apopka(config-line)#login
Apopka(config-line)#exit
4) Set the Telnet password to scan90:
Apopka(config)#line vty 0 4
Apopka(config-line)#password scan90
Apopka(config-line)#login
Apopka(config-line)#exit
5) Configure Ethernet interface (on the right) of router Apopka:
The subnet mask of the Ethernet network 209.165.201.0 is 27. From this subnet mask, we can find out the increment by converting it into binary form, that is /27 = 1111 1111.1111 1111.1111 1111.1110 0000. Pay more attention to the last bit 1 because it tells us the increment, using the formula:
Increment = 2place of the last bit 1 (starts counting from 0,from right to left), in this case increment = 25 = 32. Therefore:
Increment: 32
Network address: 209.165.201.0
Broadcast address: 209.165.201.31 (because 209.165.201.32 is the second subnetwork, so the previous IP – 209.165.201.31 – is the broadcast address of the first subnet).
-> The second assignable host address of this subnetwork is 209.165.201.2/27
Assign the second assignable host address to Fa0/0 interface of Apopka router:
Apopka(config)#interface Fa0/0
Apopka(config-if)#ip address 209.165.201.2 255.255.255.224
Apopka(config-if)#no shutdown
Apopka(config-if)#exit
6) Configure Serial interface (on the left) of router Apopka:
Using the same method to find out the increment of the Serial network:
Serial network 192.0.2.128/28:
Increment: 16 (/28 = 1111 1111.1111 1111.1111 1111.1111 0000)
Network address: 192.0.2.128 (because 8 * 16 = 128 so 192.0.2.128 is also the network address of this subnet)
Broadcast address: 192.0.2.143
-> The last assignable host address in this subnet is 192.0.2.142/28.
Assign the last assignable host address to S0/0/0 interface of Apopka router:
Apopka(config)#interface S0/0/0 (or use interface S0/0 if not successful)
Apopka(config-if)#ip address 192.0.2.142 255.255.255.240
Apopka(config-if)#no shutdown
Apopka(config-if)#exit
7) Configure RIP v2 routing protocol:
Apopka(config)#router rip
Apopka(config-router)#version 2
Apopka(config-router)#network 209.165.201.0
Apopka(config-router)#network 192.0.2.128
Apopka(config-router)#end
Save the configuration:
Apopka#copy running-config startup-config
Finally, you should use the ping command to verify all are working properly!
Other lab-sims in the ICND 1 Exam:
ICND 1 – Show Configuration Sim
Frame Relay Sim – Hotspot (on 9tut.com)
Other lab-sims might appear in the real ICND 1 exam, read and understand them if you have enough time!
2 difference that i noticed in the way the sim is solved on 9tut.com and in pass4shure,they are
1) When we assign Ip address to serial interface S0/0/0 , do we have to enter “Clock Rate 64000″ ?
and
2) After Applying Rip Protocol do we have to type “no-auto summary”
9tut please answer,Thanks
1) We don’t need to enter “clock rate 64000″ as it is not required in the question.
2) For this lab, we don’t need to type “no-auto summary” because we don’t have discontinuous networks.
You should verify the configuration with the “ping” command. For example: ping 198.18.1.1
When assigning networks in rip even version 2 i thought you have to assign classful addresses like for C shouldn’t it be network 192.0.2.0 not network 192.0.2.128
I know the router will fix this for you then add no auto-summary, but in the test it will mark it wrong unless you use the classful address.
Also confused about
no auto-summary
network 192.0.2.0
Ripv2 is a classless protocol. Look into Classless Inter-Domain Routing (CIDR).
I meant, it supports CIDR
The no auto-summary is normally entered when using the EIGRP routing protocol as it can cause issues in discontigious networks if not applied.
The reason 192.0.2.128 is used is because that is the subnet number for the address and mask combo in the example. If this were a /24 (255.255.255.0) mask given in the example than network 192.0.2.0 would have been valid when entering the command for the rip configuration. However here the range will be 128 – 144
Regardless of the version of RIP, network address has to be entered as classful in RIP configuration.
So it is 192.0.2.0 and not 192.0.2.128
I double-checked with Packet Tracer and that’s what comes up in running config.
I try to configure RIPv2 on apopka router but it’s not activate on that router. when i use show ip route command no rip is running. but when i configure rip on tampa it’s working & can ping tp 209.165.201.2 but reverse way means can’t ping from apoka to tampa interface. Problem is i can’t configure the RIPv2 on APOPKA. I am not that expert, so can anyone help me to solve that problem please.
Chengo is right, I checked it on my system too and if the 192.0.2.0 network address is not entered you won’t be able to ping the 198.18.1.0 network. no-auto summary doesn’t come into play in this situation.
How is the second assignable host address of this subnetwork is 209.165.201.2/27 ???? can anyone help !!!!
thanks
209.165.201.2 255.255.255.224 is not a network its ip address reside in network 209.165.201.0 /27 and 209.165.201.2 is 2nd ip address its self
Why assign 209.165.201.2 255.255.255.224 instead of 209.165.201.1 255.255.255.224 ? it is in the same range? it is not being use anywhere.
I just read over the question carefully and to answer farooq and calraleigh:
This is the key statement in the sim:
IPv4 addresses must be configured as follows:
Ethernet network 209.165.201.0/27 – router has second assignable host address in subnet.
——————
The question is stating that the router must use the 2nd host address, therefore this would be 209.165.201.2. 209.165.201.0 being the network address, 209.165.201.1 being the 1st host and 209.165.201.2 being the 2nd host.
It threw me off a bit as well, but I think it is just a case of reading the exact requirement of the question.
209.165.201.0 is the network address…..209.165.201.1 is the first assignble host address…and 209.165.201.2 is the second assignable host.
make me got a headache… no sleep tyte… but it vry fun…
I need to know if when the student starts the test does receive 300 pounds? In other words the score is got from 300 to 1000?
please the procedure for calculate the incremental subnetting:
Increment = 2place of the last bit 1 (starts counting from 0,from right to left)
Is valid for the class ip a, b e c ?
Help me please
I entered: network 192.0.2.128 on Apopka, and I’m able to ping 198.18.1.1 and 198.18.1.0, but yeah runnin-config is going to show: network 192.0.2.0
The question is what the exam will mark.
RIP routing protocol version 2 you have opt u can use either 192.0.2.0 or 192.0.2.128 router will not give you any error but it will always show classfull in running-config.
Hello
how can i ping and where ? I think i do mistake
I did above but I cant ping.
Apopka#ping 198.18.1.1
Help pls
Thanks
Orkinos and Tolls you have to set up to test your lab, not necessarily in the test like this:
Tampa(config)#interface S0/0
Tampa(config-if)#ip address 192.0.2.141 255.255.255.240
Tampa(config-if)#no shutdown
Tampa(config-if)#clock rate 56000
Tampa(config-if)#exit
Tampa(config)#interface Fa0/0
Tampa(config-if)#ip address 198.18.1.1 255.255.255.0
Tampa(config-if)#no shutdown
Tampa(config-if)#exit
Tampa(config)router rip
Tampa(config-router)#version 2
Tampa(config-router)#network 198.18.1.0
Tampa(config-router)#network 192.0.2.0
Tampa(config-router)#end
Then drag a Switch and an ethernet cable attach it to Fa0/0 on Tampa and Fa0/1 on Switch so you can bring Fa0/0 up line protocol is up on Tampa, otherwise it will not work; again this is only for your particular lab, then:
Apopka#ping 192.0.2.141
Apopka#ping 198.18.1.1
It should work, it has to work.
Hi,
I was just wondering if someone could confirm the RIP command? I know the router will accept it either way but which way is right an which is wrong. Would you be marked wrong on the test for entering the classless network number even though it will work just the same?
Thanks in advance!
I was wondering the same thing, what the exam requires to get a passing score, but I’m going by the ciscopress book. On page 456 and 457 said that the Network command is the only command that requires much thought. It uses a classfull network address. So whatever the interface address is you have figure it out what the classfull address is. Maybe 9tut has more input in this issue.
You can use either way and will not lose marks for them so don’t worry.
Thank you 9tut.

Hi Guys!
just ran ds simulation with packet tracer but i couldn’t ping anything from apopka router.
Why is dt?
pls help me!!!
when i did a show ip interface brief to troubleshoot on both apopka and tampa routers, it showed that the for the serial interfaces:
status up
protocol down
how do i resolve this to get pings from both routers?
pls help!!!!
success,
you have to configure the clock rate on tampa serial to 64000 since it is the DCE.

Maybe you’ll want to add a facebook button to your site. I just bookmarked this blog, although I must do this manually. Just my suggestion.
RIP V1—–> Classful routing protocol.
RIP V2—–> Classless routing protocol.
—————————————————–
RIP V1——> Subnet masks are NOT included in the routing update.
RIP V2——> Subnet masks are included in the routing update.
—————————————————–
RIP V2 is actually an enhancement of RIP V1′s features and extensions raether than an entirely new protocol.
Why can’t a IP address of 209.165.201.0 255.255.255.224 can be assigned to a interface?…It is a valid subnet IP right?
it’s the subnet address of the first subnet
With regards to having to set the clock rate on the Tampa router as it is the DCE…will this be possible in the exam, as we will be consoled into the Apopka router..will we be able to access the Tampa router directly, or is this something that the exam sim will have covered and we are just talking about this particular sim with regards the clockrate?
But it should be network 192.0.2.0 right? Not network 192.0.2.128
since it says to use RIPv2 then you cand route for the classful network (192.0.2.0) or just for the connected subnet (192.0.2.128). both work.
i don’t know about the exam environment though… maybe cisco wants to see if you are able to route only for what you have (although there is no other subnet from the 192.0.2.0 network).
why be cheap on 2 more characters? just press the damn keys!
@Jeff: You can use either 192.0.2.128 or 192.0.2.0. In the exam it will be auto-summary into 192.0.2.0 because we are using RIPv2.
9tut Thankyou for all these sims. I write in two weeks and am a lot more confident now.
Is there any place I can download these CCENT sims for Packet Tracer? I got the CCNA ones but they don’t cover these? Or do they…
Thank you very much
on this :Apopka(config-router)#network 192.0.2.128
According to what I have learned, the router will accept it, BUT for CISCO exams, it must be entered as a classful network. Therefore if you are in the exam you must enter
Apopka(config-router)#network 192.0.2.0
Can someone please email me the latest CCNA dumps. I will be taking the exam in a couple of weeks.
Thank you much

hey does anyone know if we need to use caps … for example hostname apopka or will we get it wrong if we dont use capital A for Apopka
Question… When configuring the Console and Telnet Passwords, is it necessary to enter exit following that command? Would the following commands during the test work:
Apopka(config)#line console 0
Apopka(config-line)#password RouterPass
Apopka(config-line)#login
Apopka(config-line)#line vty 0 4
Apopka(config-line)#password scan90
Apopka(config-line)#login
Apopka(config-line)#exit
Wouldn’t this be the same as entering IP address configuration on multiple interfaces? Going from one to the next since you are already in interface mode? Let me know what you all think. Thanks!
