Explanation

To configure an NTP enabled router to require authentication when other devices connect to it, use the

following commands:

NTP_Server(config)#ntp authentication-key 2 md5 securitytut

NTP_Server(config)#ntp authenticate

NTP_Server(config)#ntp trusted-key 2

Then you must configure the same authentication-key on the client router:

NTP_Client(config)#ntp authentication-key 2 md5 securitytut

NTP_Client(config)#ntp authenticate

NTP_Client(config)#ntp trusted-key 2

NTP_Client(config)#ntp server 10.10.10.1 key 2

Note: To configure a Cisco device as a NTP client, use the command ntp server . For example:

Router(config)#ntp server 10.10.10.1. This command will instruct the router to query 10.10.10.1 for the time.
