A few people have asked me about the Cisco CSR 1000v price. For lab use you can download and use the router for free, it will run with a limited bandwith but that is fine for just labbing. If you want to use it in production then you need to purchase a license which will increase the throughput of the cloud services router.
Cheers for the post, I skim read it first time and just put on ESXI 5.5 (this is a first time setup for me) & what a pain trying to get into the settings off the machines with web client. I tried Workstation, changing the .vmdk from version 10 to 9 but in the end i just gave up. Suffice to say once I threw in the towel and used 5.1 it span it up in no time!!
If you get the latest version of of CSR it does not have a 60 day eval license, it will run at 100k throughput forever. This is fine for a lab environment. The CSR 1000v routers are designed to put put into hosted environments where you would want to push some traffic through them, it is then you would purhcase a 10, 20, 50, 100Mb throughput license. For your CCIE version 5 Lab the free version is all you need.
Jezz,Most of the INE workbooks are based around 10 routers, I believe there are going to be a lot more in the lab and troubleshooting sections. Personally I am running with my 10 router setup and will use rack rentals for anything larger than that. If you can get hardware that will take 32Gb of RAM then you will be covered to run 20 routers or more.VMWare ESXi 5.1 is free and you can get a 60 day trial license. There is a lot of info on the internet about how to restore your configuration after you rebuild it after 60 days
