This is a minimal configuration for the IOS device named cs01 that is used in the hands-on exercises, so that it provides connectivity to the Management Network.

Older versions of the Cisco CSR1000V instance used in the exercises had an issue that occasionally caused the virtual router to drop its configuration on startup. More information is available at https://quickview.cloudapps.cisco.com/quickview/bug/CSCut96108.

You can use the web-based classroom interface to connect directly to the management console of the router in order to enter these commands.
