Task 1: Secure Cisco IOS Image and Configuration Files on R1 and R3.
The Cisco IOS resilient configuration feature enables a router to secure the running image and maintain a working copy of the configuration. This ensures that those files can withstand malicious attempts to erase the contents of persistent storage (NVRAM and flash). This feature secures the smallest working set of files to preserve persistent storage space. No extra space is required to secure the primary Cisco IOS image file. In this task, you configure the Cisco IOS Resilient Configuration feature.
Note: Cisco IOS resilient configuration feature is not available on the Cisco 1921 router.
Note: The output of the commands in this Task are for example purposes only. Your output will be different.
