Best Practices and Caveats

  1. When a Cisco CSR 1000v VM is deleted, not all the resources for the VM are deleted. When you create a new Cisco CSR 1000v with the same name as before, the previous resources may be reused. If you do not want to reuse these resources, manually remove these individual resources or create a new Cisco CSR 1000v with a different name.
