Gns3

Hi all

So, I downloaded GNS3....looks like a powerful tool....haven't had time to really play with it yet

I got some IOs's which aren't as easy to come by as you'd think...but anyway, got them..

Is it normal for this application to really knock the cr@ p out of your machine....?

And...has anyone got any pactice labs that cover the ICND2 stuff? different scenarios?

cheers

You have to set the "Idle PC" on the routers by right clicking on them. I had to set it on 2 different routers before my processor stopped being utterly destroyed.

usually you just want to click the idle pc on all routing devices and select the values with the * next to them.

I am not expert on GNS3, but if you have a multi-core CPU I would say install a VMware player, it is free from their website, and install a Linux OS. I use Ubuntu 10.04 64bit.
I can run GNS3 in VM without any problem; and about the resources, it won't devour your PC resources. Actually, you can multi-task in VM while GNS3 is running.
I chose VM, so that I can switch back to Windows just by hovering my mouse outside the VM window.

I forgot to specify this. One of the labs (1-7 I believe) in the link I gave specifically walks you through this.

My advice is to add a single router to the topology, wait for it to boot and then open up the consol and click no o the auto set up messages.

Give it a few min to setle down (like a pc they can still be booting and setleing down even after you have a session to them)

then do as suggested and set the idle PC value, you may want to try a few till you get the best result.

then if you go in to the hypervisor setting and make sure the idle PC value has copied across to here.

remover this router and repete with the next model you want to use.

Once you have finished you should have and idle PC value for each router when you look at them in the hypervisor settings. These values will then be applied any time you drag a router in to a project.

I found by doing the Router on its own, with nothing attached after giving it a few min to settle I can find the best Idel values. And once you ahve done it once you dont have to repete it for ever router you have in the project.
