Configuring NTP multicast mode
The multicast server periodically sends NTP multicast messages to multicast clients, which send replies
after receiving the messages and synchronize their local clocks.
For routers working in multicast mode, configure both the server and clients. The NTP multicast mode
must be configured in the specific interface view.
