I'd like to see IOL (IOS on Linux) be licensed for studying. I study at home in Florida and the electrical and cooling costs are real dollars.
I've been running GNS3 in Hybrid Mode with 3 QuadFE (AEI-P403c) nics and physical 2811s/3550/3560/3750s doing basic labs for the last month. Seems 0.8.4 is pretty stable, but still has caveats sometimes. I have to agree real hardware is the best, however it's nice that my Lenovo T420s laptop can run a small 5-8 router training lab if needed. I too have spent some time learing the ins/outs of GNS3 that I would have rather spent time on other learning! -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bob McCouch Sent: Thursday, September 05, 2013 9:47 AM To: Joe Schulte Cc: [email protected] Subject: Re: [OSL | CCIE_RS] CCIE_RS Digest, Vol 92, Issue 9 There's a lot of wisdom here. I ended up building a hybrid rack using just Dynagen/Dynamips (not GNS3) along with 3560 switches and even a couple of 1841's for a bit of real kit, but I still spent several days over the course of two years messing with it. I found the 37XX serial drivers to be wonky, so had to rework all my topos for 7200s. Found OSPF to be glitchy on the BBs when using a 2691 image for them, had to back them down to 3640s and rework the configs. Would often (esp in TS scenarios) be unsure if an issue I was seeing was definitely Dynamips, or if it was an injected fault. I upgraded my Ubuntu server one time and that flipped the VLAN offload default and my lab was broken for like 3 days until I figured that one out. And there were still artifacts from the hybrid setup in my labs (notably Port Security would always catch me because the break-out switch's MAC would be seen on ports as well as the conneted device). I just happened to be looking on eBay last night, and with 3560s in the US$200 range and 2611XMs (capable of the 12.4(15)T14 load used in the lab exam [as of 6 months ago]) going for about US$60-80, and even 1841's attainable for US$80-100 if you're patient, the cost of building a physical lab is not all that much. At least for those in the US making a decent wage. I realize the picture can be much different elsewhere in the world. I'm a big fan for a quality virtual lab, and I still use GNS3 for some functions day-to-day, and I'm also *really* looking forward to Cisco VIRL, but for intense, focused study like for the CCIE lab consider making the investment in yourself. I still use my lab pretty regularly for switching experiments. I can't bring myself to sell it off. Instead, I've beefed it up with an ASA, a small wireless controller, a few access points, and I'm even looking at how to open it up for semi-public access.
