EIGRP OSPF Redistribution Sim

the loopback interface is connected to which area ????

Area 0

ok gr8 thank you for your support.

hi
please can any one tell me why the path (R1 -> R2 -> R3 -> R4) is better than
R1 -> R2 -> R4?

I have take my Exam, I got the Question with the link between R2 and R3 using FastEthernet.
Before set Distance, the result of traceroute is : R1>R2>R4.
i still wondering, Why i must set distance 90 105 ? (Result of Traceroute :R1>R2>R3>R4).

what i remember about the Question is “R1 reach to 172.16.100.1 must using the shortest path and the Fastest Link” -> CMIIW

Can Anyone Explain it to me? Thx b4

please ?

net 172.16.100.0 is connected to OSPF ???

and which area ????

@Hassan

I guess you are trying to simulate the sim. I suppose that the network 172.16.100.0 is in Ospf area 0 the backbone (Thats how I did it using GNS3). Remeber, for no-backbone areas to pass traffic between them, the ABR´s should be connect to the backbone area at least one interface.

In this example, you are not required to pass traffic between the areas 24 and 34, but I just mencionated to make you clear.

@ASD

Im not sure what´s the real requirement for this SIM, but there seems to be 2 flavors.

- To chose the shortest path.
- To chose the optimal path.

In the first one, there wouldn´t be necessary to change the external AD, couse the path trough OSPF (R1-R2-R4) would be the shortest.

In the second one (The optimal path, as the text from this website says), we know that FastEthernet would be more optimal than a Serial Link (Talking about the bandwith).

So I guess thats way we need to change the external AD for eigrp, in order to use the path (R1-R2-R3-R4).

Before we reduce the external AD EIGRP at R3 from 170 to 105, R3 selects the route to net 172.16.100.0 trought ospf (AD 110). Then, in order to select the most optimal path, we change the external EIGRP AD to a value smaller than the OSPF AD, in this example they chose 105. it could be any value smaller than 110.

Remember when a Router have to 2 routing sources for the same prefix/prefix length, before the IOS compare the metrics it selects the better AD.

***SORRY FOR THE GRAMMAR MISTAKES. I HOPE THE EXPLANATION HELPS YOU A LITTLE BIT.****

can some1 tel me why here we use metric type 1 ? have they mentioned anywhere in d quetion like we have to use type 1 metric ??

passed today with 953 / 1000

– All dumps still valid, answers are shuffled ]

– This SIM was present and the requirement was “implement the shortest path and highest bandwidth”,,advised that the redundant link should work when the main link fails….

since it was meaning the word shortest I did not configure the distance eigrp 90 105 command,,,,,, got 89 %

Thank DigitalTut

Hi Anonymous,

routes redistributed into OSPF by default have a metric type of 2, which means the metrics don’t increment. If we use metric type 1, then the metrics increment. Metric being used by OSPF is cost, the lower the cost, the better the link is..that’s why metric 1 is used if in case the question asks us to prefer the more optimal path

I suggest you use review materials from Wendell Odom (cisco Press) and Jeremy Ciora (CBTNuggets) to understand the concepts further.

I know im probably beating a dead horse here, but which labs were on the exam please

@ Taco
all 5 configuration labs are present in the exam.

good luck all and thx to digitaltut!

Hi All,
I took the exam last week with max score.
Not EIGRP Simlet, not OSPF Hotspot.
The other 5 configuration labs are present in the exam and valid.
Link between R2 and R3 was fastethernet so I had to add the “distance eigrp 90 105″
Don’t worry if you can’t do a ‘copy run start’ in the real exam (type it and good).
Ip addresses, names, areas and processes can change!
Don’t type blind!!! Know the concept and the commands!!!
And you are on the safe side.
Thanks digitaltut, Boyi n Peter (All question from these only).

hey everyone…..
i have done this in pt everything worked well.but when i execute the command ” distance eigrp 90 105″ then i received those msg

%DUAL-5-NBRCHANGE: IP-EIGRP 100: Neighbor 192.168.1.2 (Serial0/0/0) is down: Interface Goodbye received
Router#sh ip ro
%DUAL-5-NBRCHANGE: IP-EIGRP 100: Neighbor 192.168.1.2 (Serial0/0/0) is up: new adjacency
here 192.168.12 (s0/0/0) is the link from R2 to R1 and no ping ,no traceroute working at all.

can anyone help me with this?my exam is soon…thnx in advance

@addy:
In the real exam only if the Link between R2 and R3 is fastethernet so you have to add the “distance eigrp 90 105″
imho

thnx gost.

so u mean i dont have to worry about this command anyway?
have done this exam ?

@addy:
read my post from April 4th, 2013 (3 posts above)

Does the TAB or ” ? ” work in the exam ?
thanks guys

distance eigrp 90 105 doesn’t work on my sim that I downloaded from here. How come? the link between R2 and R3 is fa0/0.

hi guys, do we need to enter the “distance eigrp x x” command on R3 as well?
Also, does anyone know how the Loopback of R4 is added to the ospf process?

tnx

ok, it’s actually working alright. you need to configure R2 & R3 first. cheers

I took the test today and this lab has evolved. It has IP’s and console’s hanging off R1 & R4. Unfortunately it came up late in the exam and I was pressing for time so I didn’t get a chance to go through everything to get details beyond what is already on this page. I didn’t score well on EIGRP, but thankfully did well enough on the rest to pull me through. Did anyone else who took the test today (or after) experience the same thing?

hi
i passed the exam today with score 976
all labs are valid but i had a problem with this lab as R1 didnt ping to the network i dont know why but no matter passed

Thanks to Allah! Passed today with good score :)
Questions and labs are all valid.

Passed today. All Sims are valid.
The link between R2 and R3 were FastEthernet link.
So need to add command “distance eigrp 90 105″ as per the digitaltut comment.
Thanks DigitalTut.

can anyone please answer me , Does (TAB ) or (?) work in the exam ?

what happen to examcollection site? it’s not working. Do you have any idea?

Abdulrahman Keilani – Yes, Tab worked on all the labs and so did the “?” command

Hi Everyone, Can someone pls. tell which labs are coming in the exams and which dumps are valid…Thanks

in the exam we will assign the ip address to router and define the protocol used or we will start by the redistribution ??

Hi CCNP,
Could anyone who passed out recently send the lab Sims name please??
Any one got c2691 ios image link for GNS. Please send the link.
Appreciate for your kind help in advance.
Regards

Hi All,
I would like to mentioned one more thing here,We need to redistribute EIGRP in OSPF on router R4 as traffic will go to it but will not get reverse path for it since we have only redistribut the EIGRP OSPF and OSPF in EIGRP on router R2

can anyone pls forward me the simulation lab to ma mail id : mertinkit@yahoo.com

please can any one tell me why the path (R1 -> R2 -> R3 -> R4) is better than
R1 -> R2 -> R4?
Im not sure what´s the real requirement for this SIM, but there seems to be 2 flavors.
- To chose the shortest path.
- To chose the optimal path.
i m confused plz fast rply my paper is 24/04/2013

@Asad,

The path R1>R2>R3>R4 is better because the link btw R2>R3 is fastethernet which has a better bandwidth than the serial link between R2>R4.

what is interfaces used to connect between R3 and R4

A QUESTION,

how can R3 to R4 is most optimal route, because when traffice reaches on R2, if it goes to R3 it passes on a serial link and then it will reache to R3 but in the same time it can reache to R4 because of another serail link is between R2 TO R4. So how can we say it is the most optimal route, In any case ( short route or optimal route ) , to cross 2 serial links are much better than cross 2 serial link with extra FASTEHTERNET LINK or ETHERNET LINK.

please clear my concept with example.
thanks for all.

ok
thanks CONSULA.

Passed today, this lab was present and the the links between R1-R2, R2-R3 were both fast ethernet, the requirement was for the traffic to go through the shortest path with the largest bandwidth, So i did like exactly here and got full mark

Thanks to Almighty Allah passed the exam today got all the labs and no sims…988/1000 ….. only the ip’s and areas were changed and in this lab it asked to ping and telnet ….it wasnt letting me telnet but still got full marks.. thankyou prepared from Igor 395 and boyi 411 they both are the same and this website is awesome …Good luck to everyone …

Hi
We don’t need to add subnets in redistribution because all network in the diagram are classful

Is it really necessary to use the distance eigrp 90 105 and where exactly do you configure that?

hello all,
can anyone please assist me here understanding the 5 interface paramters on R3.
which interface 5 paramters are we using in our redistribution of OSPF on R3 …
I mean if I wanted to find out the 5 parameters on R3 … for which interface should I do the show command on … all I hear it is the fastethernet link …

I need help please …

to be more clear about my question above,
in the picture for this question at top of page, we see where int s0/0/0 is ,
that is clear to me
but for the other interface on R3 , the picture here doesnt show which one … are we talking about the interface on R3 facing R2, or the one on R3 facing R4 … I need to know so I know where to apply the distribution

please please …..

i used command distance eigrp 90 105 but still route was taken R1–>R2–>R4 only. link R1and R2 is serial and R2 and R3 is serial, R3 and R4 is fast ethernet. how 2 trouble shoot this?

plase send me labs i have exam on 30th

Test had all the hotspots shown here & multiple choice questions were from the ones listed. Test is not a walk in the park, so study hard. Must keep an eye on the clock for time left, or you will fall behind.

took this test yesterday.
the link between R2 and R3 is Fastethernet.
so

R2(config-router)# distance eigrp 90 105

is required.

passed, but didn’t score that great due to too many IPv6 & Tunneling questions. I was expecting perhaps a couple of questions on the subject, but got about 3 tunneling Qs and about 15-18 IPv6 Qs. I do advice reviewing those if you want top scores nearing the 1000th

Were the IPv6 questions from this site?

Hi
Why do we need mutual redistribution on R2 and R3, I think the redistribution from ospf into EIGRP is enough, because the requirement in the lab said that we should only ping from R1 to R4, i did that in GNS 3 ans it works.
Correct me if I’m wrong please

@Noureddine: No, you can’t ping from R1 to R4 because R4 needs to send reply back to R1 -> mutual redistribution is required.

can anyone email me any of the ccnp routing labs they have on packetracer or gns3 plz….email is yaly1975@yahoo.com…thanks

I have passed route yesterday with the score 790/790 at my first atempt. Tks by the labs, I had to solve the EIGRP OSPF Redistribution Sim, Policy Based Routing Sim, IPv6 OSPF Virtual Link Sim, EIGRP Stub Sim and OSPF Sim.

Just wondering should I turn off the auto-summary in the EIGRP config in each router?

Thanks,

is there a GNS lap or packet tracer for this quis????

Hi
Hamdolillah, passed today with high score 1000, all questions are from examcollection (peter) and 5 labs from digitaltut (thanks a lot).
Tab and ? works in all lab.
don’t worry if the command copy run start doesn’t work, just type it.

Steve,
No you shouldn’t do that, just do the same config and it works.

Concerning the use of “usec” in delay’s millisecond unit [in Answer and Explanation, pp 8] :

“usec”- the u is used as a alphabetical stand-in for the Greek letter “mi” which is written scientifically as “μ” or “μsec” (millisecond). Cisco can’t provide Greek letters in CLI.

Can someone please help me out? I’ve gone over this lab several times and I cannot get it right. When applying the configs, I have no problem obtaining the shortest route when pinging from R1 to the Loopback on R4. However, even when changing the distance (90 and 105)on R2 and R3, I cannot force the route to the faster connection (R2, R3, R4). Please advise where I am going wrong.

@ Can’tGetRight!

the distance command must only configured on R2 router

@ Noureddine,

I tried that initially and I still wasn’t able to force the route to R2-R3-R4.

Thanks to all in Digitaltut for helping me to pass the exam. All 5 sim labs appeared in the test. For this question, I included “distance eigrp 90 105″ in R2, because the interface between R2 & R3 is FastEthernet. Good luck to those taking this exam.

Just passed Route today, thank you Digitaltut! I just donated something, keep up good work. For this lab, the requirement was to configure distance in such a way that the path with best bandwidth is preferred. I am not sure now, as I am still dizzy from the exam, but I think path from R2 to R3 in the exam is also an fastethernet (not serial), as it is the path from R3 to R4. So, the path with best bandwidth is R1 -> R2 -> R3 -> R4 and solution presented before is valid (R2 -> distance eigrp 90 105)
In addition, all labs presented on this site were in the exam and presented solutions are valid. Only few questions that are not in this website were in the exam. Thank you again for the good work.

Anyone get a perfect score on this lab? Just wondering about the “metric-type 1″ command. I don’t see anything in the instructions about going away from the default E2 route or anything about making sure the metric increases.

Thinking cisco may take some points if you change the default without it being an objective in the lab.

hi all
i’m from indonesia
pass my test yesterday
got all 5 sim question
all dumps still valid, but shuffled
good luck for those taking the exam

thank you digitaltut

yggTQl Great, thanks for sharing this post.Really looking forward to read more. Really Great.

how can i calculate bandwidth??if i m not using 1544 than how can i use 128??is there any specific formula??

plz reply soon

KjsPFZ TestGbjwori

Can anyone provide the GNS3 configs for these labs? I’m a bit of a Newbie?

Passed today with 1000 points. They wanted that packets use maximum bandwidth available and link between R2 and R3 was fastethernet so I put command distance eigrp 90 105 on R2 and got 100% of points.

passed today with 921 / 1000
