![]() ![]() It’s almost like the CSR1000V is not optimized for lab use? IOU Excellent – but it’s only three hosts, and it’s a lot of resources to eat up per host. With the help of Jeff’s excellent guide I was able to get three CSR1000V instances up and running and talking to each other. I haven’t dug around much to find out I was just pleased that I could download it and install without having to hand over a fat wad of cash. I keep wondering if that’s a mistake, or if they know that the 1 vCPU version is so powerless that it simply can’t do anything useful on its own, so it’s safe to download. I’m not using it for business, just for my lab, so it’s nice to be able to grab a copy like that. To my surprise, just as Jeff said, I was able to download a copy of the CSR1000V OVA image without anything other than accepting the licensing terms. In particular, that seems like an awful lot of memory to soak up, especially when you think back to how little RAM Cisco routers have typically come with over the years. That’s not a terribly onerous requirement by any means, but it does mean that for each router I want to run, I need to have 1 vCPU and 2.5GB of RAM. CSR1#sh verĬisco IOS XE Software, Version 03.11.00.S - Standard Support ReleaseĬisco IOS Software, CSR1000V Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 15.4(1)S, RELEASE SOFTWARE (fc2)Ĭopyright (c) 1986-2013 by Cisco Systems, Inc. The CSR1000v runs IOS XE and specifically, it runs one instance per VM. That I can handle much more easily, and in fact I can run a few of those at the same time without killing my VMware server. Instead of four vCPUs I now only need one vCPU, and the RAM requirement has gone down to 2.5GB. ![]() ![]() The decision to shelve the CSR1000v as a home use product turns out to have been somewhat hasty as in the next release (3.10), the requirements were reduced: Then I considered how much this was likely to cost as well, so I noted the product and put it our of my mind as something I could run. At least, in my environment I don’t have CPUs to throw at stuff just for fun. Last time I checked the CSR1000V requirements, this is what they were:Īs you can imagine, with a requirement for 4 vCPUs, my reaction was that this was absolutely not something I would want to deploy at home as it’s just not scalable to have more than one VM running like that. I was a little surprised though because last time I checked out the CSR1000V it simply didn’t look like something practical to run at home. This is a great post (please do click through and read it) explaining how to get, and install, some instances of the Cisco Cloud Services Router (CSR1000V). To that end I’m a big fan of solutions like GNS3 that allow me to virtualize my environment and build out simulations without needing to fumble with a bunch of Cat5 cables to build my desired connectivity.Īnd so I really enjoyed when today Jeff Fry published a post called Cisco CSR1000V Home Lab Setup and Configuration. While I love hardware, I really don’t like the space it takes up in my house, nor the noise it makes (rather ironic given the noise levels emanating from my network closet, but still…). ![]()
