What is the best computer to build for gns3 ccnp? I am looking to build a computer in the spring, after my ccna, just for gns3/cisco. I will not be using this computer to game. It will just be for gns3/homework I want to be able to run 10 routers and not be running to high.
Running it fine on a Win7 64 bit machine with Core2 Duo and 4GB of RAM. As long as you set the idle-pc values correctly and use a GNS friendly router image (I use the 3725's), you should have no troubles running 10 routers.
You could also check out the forums at http://7200emu.hacki.at/. You will find a huge amount of information there! Also, as johntaddeo says, get your idle-pc values sorted properly - read the forums carefully on how to do this.
Also depends on what you're doing. I've used Dynamips on a 4 year-old laptop and desktop, neither particularly grunty (1M RAM, a fairly standard CPU) and had 10 routers running easily. But I was only testing a specific feature each time - for example, BGP confederations.
1. More RAM = More GNS routers; so 64-bit capable box is ideal for gns3 due to limit of RAM support by OS. 4 GB up to 8 GB would be enough.
2. CPU - I think Intel runs better than AMD, 2 are OK, 4 cores are better. Weaker CPU means higher CPU utilization. i5 or i7 are perfect.
3. NIC. get if you can dual NICs and ones that will support VLan tagging 802.1q (do not strip Vlan IDs from frames). 802.1q matter if you want to do router-on-stick.
Some NICs support Vlans and priority which could be handy to do some QoS.
Why do I want 2 NIC's and why do I want router on a stick? I think were about to learn this in the next few weeks. I'm still a little ignorant. Yeah I'm thinking i5, I mean its half the price of the i7, 8gb ram.
oh, you can do router-on-stick totally inside of GNS3;
or you can use GNS router and connect real switches to GNS.
you will need 2 x c3550 EMI or SMI switches as well;
btw. router on stick is on CCNA now.
even 4 GB is OK for 10 routers; make sure you new motherboard supports more, like 8, 12 GB.
Make sure you will have 2 PCI slots free to add special NIC or usb ports.
Yes, you can connect any real device to a GNS3 using Cloud in GNS;
if you drag and double click on Cloud, you have configuration page; there you see all your NICs installed on PC like MS loopback, any VMWare NICs, and so on,
MS Loopback is handy to communicate with your Host PC; you can ping from cmd of Windows to GNS3 router interface if you connect and set up properly;
what is "pic"
well, u can use GNS3 for CCNA; especially when you router is broken;
Just remember that GNS3 routers will have interfaces UP UP even thou there is nobody on the other end; just one and the only one flaw of GNS3 emulating its interfaces.
Yeah I agree but my computer doesn't do too well with gns3. Thats why I need a new one. There could be a lot worse flaws. I think gns is great and now that I am a little better informed I think it was a waste to get the real equipment. I mean im glad I did since I don't work in networking field but for ccnp def just use gns and keep my 3550 switches.
Can I hook a cisco phone up to one of my switches and it run through my nic and still see the phone on the cli?
If I remote desktop to my computer that is running gns does the computer I am physicaly on have to have a good cpu and ram too or does it base it off the computer I am remoting into?
If you for CCNP only you can take core i3 with 4GB of RAM and if you want for further you can buy core i5 with same 4GB of RAM and there is one more processor os there you can buy AMD Phenon 2 that also has good power with 8MB of cahce memory.
Thanks & Regards,
IP phones will need files from tftp server and have to be settup on Voice router;
to se if your IOS supports VoIP do this:
in config mode type : telephony-service setup
if you got wizard, you are OK, in there is an error, try telephony ?
if your switch does not support power over Ethernet then you also need power brick for phone;
Remote PC does not need to be powerful pc;
Your welcome buddy. Yeah choose anyone of this beacuse all are having good power but pricing is different different.
Thanks & Regards,
