Use the ntp-service reliable authentication-keyid command to specify that the

created authentication key is a trusted key. When NTP authentication enabled, a client

can be synchronized only to a server that can provide a trusted authentication key.

authentication key as a trusted key.

No authentication key is configured to be trusted by default.

If you do not wish the IP address of a certain interface on the local device to become the

destination address of response messages, you can use this command to specify a

particular interface for sending all NTP messages, so that the source address in all NTP

messages is the primary IP address of this interface.
