there should be a clock rate configured to router 1? am i right?

By: jokerdc

jokerdc — Thu, 10 Apr 2014 13:00:03 +0000

it works simply because there are not discontiguos network…. the networks pass trought R1 that handles both 192.168.30.x and 192.168.60.x classes

By: jokerdc

jokerdc — Thu, 10 Apr 2014 12:45:59 +0000

I think it’s no needed to use ” no-autosummary” command because 192.168.30.x and 192.168.60.x are in Class C Calss so they will be summarized as 192.168.30.x and 192.168.60.x and no as 192.168.0.0. I tried whitout no-autossumary in any router and it works!

I am getting the error message

*** Error: 209-unable to start VM instance ‘ghost-c2600-bin-mz.123-6f.bin-localhost.ghost’

When opening the troubleshooting scenario. I have a 2600 image, but it’s not exactly the same; is this causing the error?

Guys Its Time to update the Simulations don’t you think SO ?

By: sampem

Maybe you’re to use telnet from the main router to connect to the other routers if there was no direct console connection! you must have missed that. I’m also preparing for mine. Good luck next time.

Hi 9tut, I did the examination today and unfortunately I failed 720…….I was given a console into the main router and had to configure all the rest of router interfaces but no matter what I did I could not open the rest of the routers……..Double-clicked, you name it and I just couldn’t get into any of the rest……If one is only consoled into 1 of the routers, tell me how do I access the rest…….? I might have missed that instruction and maybe I was doing some thing basically WRONG? I understand theories and every thing else but……This just didn’t work for me today?

@confused candidates
Line is UP – you have used the correct type of cable, the devices are powered on
Protocol is DOWN – L2 problem.

my guess: if using serial links – you forgot to set the clock rate on the DCE router, right?

That the letter “E” is taken by EGP may explain why EIGRP does not use the letter “E,” but it does not answer the question: Why does EIGRP use the letter “D?”

The letter “D” stands for DUAL, the Diffusing Update Algorithm. DUAL is the programming that dictates how EIGRP chooses least-cost loop-free routes, and makes for a much more interesting answer, IMO. :)

It worked for me, thanks 9tut!!
I was not uploading the image. I thought it came with this EIGRP lab but that wasn’t the case (I couldn’t find it, please correct me if I am wrong). I downloaded ‘c2600-bin-mz.123-6f.bin’ image from the internet and pointed the image path to it and changed ‘working directory’ and it worked.
P.S. It is a big memory hog. I still like Packet Tracer better than this in terms of configuration and memory issues.
Does any one has a say on it? :)

By: 9tut

9tut — Mon, 24 Oct 2011 08:12:11 +0000

@Nash D: You have to change the “working directory” & “image” path in .net file to make it work well.

guys, this is not directly related to the topic..but had a little problem lately on how to save my gns3 labs then load it..but i had it sorted out…just curious on the working folder that is created after you save a project…what is that folder for? when opening up a project, we just need to import the configs right? and has nothing to do with the working folder? what are the uses of the files in the working folder?
