Let’s face it we can do so much with GNS3 out of the box, it’s an amazing tool, especially with the way GNS3 1.0 is shaping up. However, Cisco is moving at a pretty big pace and there is a whole new line up of devices that we can use that are not supported in GNS3 (natively). Thankfully those wise people at GNS3 have leveraged VirtualBox to make our lives easier, and our topologies better and more up to date.

Today we will start having a look at the CSR1000v, we will cover downloaded and installing in VirtualBox, as well as changing our license level. Th4e CSR1000v is a free download if you have a CCO account, which is also free, so really you have no excuses.

The CSR1000v is a virtual router designed to run under VMWare or, as we will be doing here, under VirtualBox.

Getting the CSR1000v

You can download the CSR1000v straight from Cisco with a valid CCO account. The download link is here. Download the ISO image.

Installing the CSR1000v in VirtualBox

Fire up virtualbox and create a new 64-bit Linux VM (using “Other”).

Once it has installed and rebooted we can see that we are running IOS XE 15.4

We are also running on the standard license, though even if we do change the license level (as we will do next) both still show “License level: limited”.

Licensing

At first run the CSR1000v has loads of options for us to play with, but we can make these even better. If we drop into the configuration mode and do a “?” we can see what’s available to us. I won’t copy out everything here, it’ll just waste your time and mine reading through everything. But there is loads of stuff. But we can have more.

We can change the license level and get loads of cool new stuff, and who doesn’t like cool new stuff?

The license level is changed by doing the following:

Router(config)#license boot level premium
         Feature Name:prem_eval

(lots of EULA stuff - removed for brevity)


ACCEPT? (yes/[no]): yes

*Jul 22 12:49:06.561: %LICENSE-6-EULA_ACCEPTED: EULA for feature prem_eval 1.0 has been accepted. UDI=CSR1000V:96RG3ZZC37F; StoreIndex=0:Built-In License Storage% use 'write' command to make license boot config take effect on next boot

Router(config)#exit
Router#wr
Router#reload

I did try changing to the advanced level, but this crashed the router. Once we have reloaded our CSR router we now also get (and I am just showing the new options):

Impressed yet?

We will start to have some fun with this in another post when we get it connected to GNS3 and build something fun to play with.
