Description
Using ntp-service source-interface command, you can designate an
interface to transmit NTP message. Using
undo ntp-service source-interface
command, you can cancel the current setting.
The source address specifies where the packets are transmitted from.
You can use this command to designate an interface to transmit all the NTP
packets and take the source address of these packets from its IP address. If you do
not want any other interface to receive the acknowledgement packets, use this
command to specify one interface to send all the NTP packets.

their source IP address.
