Explanation:
You can configure the Cisco CG-OS router to authenticate the time sources to which the local clock synchronizes. When you enable NTP authentication, the Cisco CG-OS router synchronizes to a time source only if the source carries one of the authentication keys specified by the ntp trusted-key command. The Cisco CG-OS router drops any packets that fail the authentication check and prevents them from updating the local clock.
