CCNA Configuration SIM Question

Hi Ricky-ricky,

We put no auto-summary for the same reason we do it in EIGRP so that the addresses show up as they have been subnetted and not summarised to their classful boundaries.

Hi MSP,

The as Anton said the command syntax was wrong, but also this sim is not to verify that you can confirm routing works on the network. This sim just wants you to configure RIPv2 on the specified router and thats it.

But i must admit i was confused too with this SIM trying to check if routing is working across the network.

hey ..

how can i view all the .vce files . i have a player but its only a trial version which allow only 5 questions. Please help me on this

thanks :)

Hello friends..
how can i know which serial int should be set as the clock rate on it? s0/0/0 or s0/0/1? is there any command for that? thanks..

@Myeyesburned:
show controllers s 0/0/0
Interface Serial0/0/0
Hardware is PowerQUICC MPC860
DTE V.35 TX and RX clocks detected
……

please help me in simulations because when i am practicing in dumbs simulations are not working there.

where are “no auto-summary”?

at ripv2?

is the R2-RC only router that can be used in this lab? if yes how can u ping the R1. in .PKT no clock rate is set on R1.

Hello all.
I would like to repeat above question again.
During RIPv2 configuration…do we have to use “no auto-summary” command?
Do we loose points if we don’t?

Thanks!

I need it’s needless to use no auto-summary.

If you want to see correct results with show ip route:
Go to R1-RT and add command “clock rate 64000″

hi all,is this sim already on the CCNA exam?

the no auto-summary command isnt needed because the network isn’t discontinuous. If it had been say 172.16.xx on each end with the connection between the routers as is then no auto-summary would be needed.

notice “you have to use no autosummary here for rip the send network subnet in it’s packet and you have to configure the clock rate on the int s0/0/1 on R1-RT to able to make the network network convergence.

use ip int b to see if a serial connection is up/down (signifying no clock rate) use show controllers command to determine which side is the dce end (ie the one that needs clock rate) for the serial connection. and again “no auto summary” isnt needed, you can apply it and the network will work but in this instance its not required. auto summ will summarize to the classful boundary, in this case all are Class C, so you would have 192.18.1.0, 192.0.2.0, and 209.165.202.0. 3 distinct networks. However I am referring to the listed problem and havent looked at the packet tracer.

@eagle
I’m referring to the packet tracer ! the DCE one is on R1-RT and if you dont put the no auto-summary in the network will be like this

Gateway of last resort is not set

192.0.2.0/28 is subnetted, 1 subnets
C 192.0.2.16 is directly connected, Serial0/0/1
C 198.18.1.0/24 is directly connected, FastEthernet0/0
R 209.165.202.0/24 [120/1] via 192.0.2.30, 00:00:15, Serial0/0/1 (this is a summary instead /27 which summary some unknown network which could cause the routing loop)
R1-RT#

Is there a way of resetting your sim in the CCNA lab simulations? Sometimes i play around with a sim/ do something really wrong and cant fix it. Is there like a button or something to reset all what you have done and start from scratch?

If you go into CLI of router, R1-RT and check sh controller se 0/0/1, you will find that it is a DCE router and clock rate is not set.

To set the clock rate on R1-RT router

conf t
int se 0/0/1
clock rate 64000
end

The interface se 0/0/1 will come up on router R1-RT
The interface se 0/0/0 will come up on router R2-RC

I don’t know if we have to do this in the exam though. If someone knows please let me know. Thanks !!

Do we need just configure _new Router_, or both of them ( including R1-RT) ?
Should be connection tested between parts of the network ?

If so ( I mean to configure R1-RT as well) we need rise up RIPv2 on him, configure for existing networks and configure clock rate on “s 0/0/1″. After that we can see remote networks advertised by RIP

do we have to set clock rate on R2-RC router ?? if so then how will we know what clock rate is set on R1-RT router in exam

in the real ccna exam when i want to configure the router i have to access the host to configure it or i can go directly to the router and make the config there…
{Q.To configure the router (R2-RC) click on the console host icon that is connected to a router by a serial console cable } plz answer me ASAP

exact same problem! So f’ing aniynong And when it does work it’s a bit slow n if the phone rings or someone uses it then that cuts the connection for a bit which is infuriating.. It’s 2011.. That shouldn’t be an issue anymore Can’t find a solution either Already have router and phone wires separately feeding into wall socket through a splitter thing that then plugs in on it’s own but no change Infuriating

Hey,

With regards to RIP – the lab will work fine if you configure the routers correctly.

Here’s the answer with the breakdown:

The routers are connected via serial links. Serial links require the following:
* Ip address and subnet mask
* Encapsulation
* Clock rate set on the DCE side (show controll s0/0/0 shows this in a real environment, no here though)
* Bandwidth

If you want RIP going it needs to be set on R1-RT as well.

None of this is set during the lab question – it isn’t required for the answer (from what I can see above). If you want the line to come up (ie the routers to see each other) you need to set it on both sides. You should already know something is wrong because you can’t ping the routers over the serial link.

Here is the runing configuration exerpts:

R1-RT:
interface Serial0/0/1
bandwidth 64000
ip address 192.0.2.17 255.255.255.240
encapsulation ppp
clock rate 9600

router rip
version 2
network 192.0.2.0
network 198.18.1.0
network 209.165.202.0

Router R2-RC:
interface Serial0/0/0
ip address 192.0.2.30 255.255.255.240
encapsulation ppp

router rip
version 2
network 192.0.2.0
network 198.18.1.0
network 209.165.202.0

And the route outputs:

R1-RT:
show ip route
192.0.2.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.0.2.16/28 is directly connected, Serial0/0/1
C 192.0.2.30/32 is directly connected, Serial0/0/1
C 198.18.1.0/24 is directly connected, FastEthernet0/0
R 209.165.202.0/24 [120/1] via 192.0.2.30, 00:00:01, Serial0/0/1

R2-RC:
show ip route
192.0.2.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.0.2.16/28 is directly connected, Serial0/0/0
C 192.0.2.17/32 is directly connected, Serial0/0/0
R 198.18.1.0/24 [120/1] via 192.0.2.17, 00:00:20, Serial0/0/0
209.165.202.0/27 is subnetted, 1 subnets
C 209.165.202.128 is directly connected, FastEthernet0/0

Knowing what you need on a serial link to get it up will make troubleshooting a lot easier :-)

Cheers,

@IT Guy,
I understand that for the RIPv2 to work fine, they must be configured on both routers. it is only a matter of confusion,,, that the question doesnt ask for any configuration on router1, Did the system marked your answer correct when you also put a configuration on router1?

The question didnt require for a successful ping after configuring router2… My concern is we are after the POINTS that we can get on this LAB sim, that for as long as we input correctly what we are asked to do, then is it still matter if network converged?

Just a question? Since the line asterisked below is on by default, is it needed for point purposes?

R2-RC(config)#line vty 0 4
R2-RC(config-line)#password cisco3
**R2-RC(config-line)#login**
R2-RC(config-line)#exit

Qustion
do we need to advertise networks that are directly connected.?or just network 198.18.1.0

Hi Everybody,

Can somebody send me the registration key for the certexam suite so that I can view the dumps. Thank you much…

Just want to take time and thanks every one contributed in this web page .

Can someone please explian what “network isn’t discontinuous” means please..

I have always been really confused on this. and i dont get it..

From what i know already, i thought if it not you classic class A,B,C address then you need to use the no auto-summary at the end.

I really need some help on this as i really dont get it..

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 networt

I’m really confused… Please explain. I thought as there were not private address they need the “no auto-summary” command

hi everyone!
Which statement is correct regarding the operation of DHCP?

a. If an address conflict is detected, the address is removed from the pool and an administrator must resolve the conflict.
b. If an address conflict is detected, the address is removed from the pool for an amount of time configurable by the administrator.

Which one is true??? At 9tut the answer is a , at Brar the answer is b. I am not sure what is right!!!

i think if you are using vlsm you need no auto summary, if you use classful network. like 192.168.10.0 there is no need, cuz rip knows that it has 24 subnet. is there anyone to confirm me? because im not sure also.

@IT GUY

You don’t need to do

network 209.165.202.0 on R1-RT because the route will be learned thru R2-RC if rip is being configured on both routers.

if u want to ping from r2-rc to r1-rt or vice versa..den jus connect a serial with its dce at r2-rc and terminate it at r1-rt…njoy pinging..:P

guys finally just u debug the packet it will exchange the updage..give debug ip rip wait for 30 seconds work perfectly..

What I have noticed with this SIM is that the clock rate is not set. Therefore you cannot ping to s0/0/1 or beyond because the protocol is down. once you activate the clock rate everyone talks to one another. Is this something that will be in the actual SIM?

@Joe: No, you don’t need to set the clock rate in the actual exam.

clock rate on interface s0/0/1 of router R1-RT is not set,thats why i’m not getting route about 192.0.2.0 network.after setting clock rate on s0/0/1 i got route info(as this task not mention to do).
is it necessary to give clock rate on s0/0/1 on router R1-RT in exam ?

@ Shanku, as 9TUT said, no… It is not needed Shanku. Thanks for the clarification 9tut.

Pessoal esse configuração do rip esta errada, pois as redes que deven ser anunciadas seriam as 192.0.2.16 e q 209.165.202.128 pois o RIP v 2 suporta vlsm no caso da configuração das redes anunciadas teriam que ser as redes quebradas.

alguem pode comentar mais a respeito??w

what is the destination file in nvram for copy run start?

can anyone tell me how to open the .vce file…

Download & instal visualcertexam manger(vce) software latest version and now open…

Priyanka,

You can download only trial version It works 45 days only. You might be found duplicate one if you search the internet

As I think , from above sim there need to be configured RIPv2 with “no auto-summary” command.Because only OSPF doesn’t need to configure “no auto-summary”.
In addition , for run vce file you need to download Virtual Exam Suite pro.
Hope it helped :)

We need to set the clocking as well for the DCE serial interface to work between the routers as it is not done in above solution.

@Irtaza how can we set clocking ffor serial interface

@dce the R1-RT router has the clockrate set. I don’t think the R2-RC router needs the clockrate set on it’s interface.

Exactly “Just for help”. What about no auto-summary?
