NTP multicast mode configuration example

Network requirements
As shown in
segments and synchronizes the time among multiple devices.
Router C's local clock is to be used as a reference source, with the stratum level 2.
•
Router C operates in multicast server mode and sends multicast messages from Ethernet 1/1.
•
Router D and Router A operate in multicast client mode and receive multicast messages through
•
their respective Ethernet 1/1.
