C3725 Advipservicesk9 Mz 124.23 Bin
Latrisha Adan
I am using windows 10 and I tried to open router console in gns3 and get this massage in console window(Connected to Dynamips VM "R1" (ID 1, type c3600) - Console port Press ENTER to get the prompt) when I pressed enter nothing is happen. no error no anything. I installed versions (GNS 0.8.6 , 1.3.13 , 1.4.6 and the last version) and used a lot of images like (3640 and c3725-advipservicesk9-mz.124-18) but the same issue is still.Is anyone faces this issue before ?????
I can confirm that accepting the default RAM entry will solve this issue. I was clicking finish without an idle-pc value found. After accepting the default RAM, the wizard found an idle-pc value, and then I was able to finally connect via putty.

Show Quoted Text Right, the 3725 doesn't have tftpdnld.. It has xmodem though! If all else fails, jack the console baud rate up to 115,200, and xmodem in the smallest IOS image you can find. It might complete in 4-5 hours for you... Depending on size of course. This is not going to complete quickly.

Show Quoted Text Are the files valid? A common problem is using ftp ascii mode to transfer the files. Use binary mode always. Just to be clear I am not taling about the xmodem transfer but a possible earlier ftp, perhaps from the cisco web site.

"O" is out of order packet. Make sure that you don't have a duplex mismatch between the client and the server. tftp is not good at recovering from errors. Start with everything at auto-speed/auto-dup.
Some old tftp clients has bugs. I forget the details now. Use tftpd32.exe if you are on Windows but make sure that it's dhcp server does not cause problems on your network. tftpd32.exe is a perfect tftp server - except that if now comes with unwanted baggage:-)
Show Quoted Text I had this once with a tftp server : the image got stuck at the same point during transfers (I always check CRC before uploading) I changed the tftp server to tftp32 (from Jounin) and it ran fine (the upload) As the problem was fixed I did not take time to look for the exact reason why (interactions with Antivirus, mem corruption on my laptop, anything more strange ..)
As Dan has mentioned on the other thread you started, use ftp instead if problems persist. If you use Windows Serv-U is easy to get going. If the server insists on a username/password they look like this on the cisco command line.

Do you want your CCNA or CCNP Certificate?The How to Master series helps you to understand complex topics like spanning-tree, VLANs, trunks, OSPF, EIGRP, BGP and more.
I could but there are many components in between that could cause the issue. What did you verify / exclude what the problem could be? You can also take a look at the sample of my TSHOOT book. You can read the chapter where I walk through the troubleshooting of this lab for free.
The lab has worked fine( only some edits are required in the .net file). Rene you are really a great guy. Now I am pretty confident that I will be able to nail down the CCNP THOOT EXAM in near future. Rene, thanks a lot for these superb labs.
You are going to have do some edits in textedit to the.net file. If you read my issues above, I had similar problems. I edited the aux ports to be different ports for each instance. There are other issues that you may need to address like the length of the file paths, no spaces in the paths.
You have done great work here. One thing though. What are these static mac addresses that are added to DSW1 and DSW2 configs. Where do they come from and why are they needed? Can the switches not learn them dynamically.
Pls advise as i get an error message when i try to load the topology. i have loaded the same IOS image and still no luck. If there is anything i can change please let me know what to do to get it working
then open the GNS3 app and click on EDIT>>PREFERENCES and click on Dynamips to left of window. look for the BASE AUX PORT: and change it to start at 2100 TCP. default in windows looks like 2501. Or you can leave this alone and change the numbers in the topology.net file and start the port numbers from 2501 down the line for all devices.
Once you have your ios setup in GNS3, place 2 c3700 routers on a blank page and connect them via serial and start them. click CTRL-SHIFT-ESC to open up the windows task manager so you can monitor performance as you now have to set the IDLE PC value. Once you get that done and your cpu drops to 0 or very near it then you are good to go.
Note1: It looks like he created this topology under Linux O/S or similar as you will notice in the .net file all the paths have a forward slash /.
No need to change anything here because GNS3 recognizes the change and modifies the file. Once you successfully open the lab topology and save it, if you reopen the topology.net file you will see all the paths changed to whats on your PC.
Does anyone have any ideas about how to solve the "lost connection error". I am tying to open the lab on windows 7 and I keep getting this error. I have downloaded the c3725 image Rene instructed we should download but it does not open. Any help.
There are errors in the original topology.net file. Here is a link to replace the one you downloaded with the one I fixed.
Just delete and replace with this one. Then as long as you have a c3725 image setup in gns3 it should work. Dont forget to setup IDLE-PC !!! Just start about 3 or 4 routers and wait a minute or two then do the idle-pc.
no need to change any other lines. this is because as long as you have the image setup in gns3 and everything else in gns3 is working, then once you open the topology and SAVE, gns3 makes the changes in the file according to what settings you have setup in the gns3 program itself. so, just download the fixed file below..
Once you replace the topology.net file and try to start it for the first time, it will ask you which image to use. Just select the one you saved and after it loads up, save topology in gns3. Thats it !!
I have same problem as avesimasud above. Its a shame cant get it working as site looks great and would help me finish my CCNP. As I am not the only person experiencing these problems would it be possible to get any definitive advice on how to load the topology into GNS3?
PCDOCTA my apologies for being so hasty in my comment. I was in panic mode as I found Tshoot very different from switch and route. Glad to say it is working now having downloaded your modified network file and many thanks for your interest and help to people here..appreciated. Jezza in Dublin
I am a bit stuck on the 3rd ticket. There is no default route to the BGP network from ospf. I can do a redistribute bgp (I dont think this is a good idea especially if you receive a lot of routes from the ISP. To redistribute all that routes might make the router slow) or using a static route with the default information cmd. There is not specified what is the company policy would like us to do.
Hey! Thanks so much Renee. This is a great lab. I rebuilt it from scratch so I would really know the ins and outs in preparation for the big exam next week (TSHOOT). As per a comment I saw on the Packet Pusher Podcast, I am going to use this lab, and have my boss or co-worker go in and break something random a few times each day, so I can tshoot it in preparation! Great stuff Renee! Thanks again.
