Ntp Multicast Mode Configuration Example - H3C SR6600-X Configuration Manual

The following uses Router A as an example to describe configuration verification.
# Verify that Router A has synchronized to Router C, and the clock stratum level is 3 on Router A
and 2 on Router C.

NTP multicast mode configuration example

Network requirements
As shown in
segments and synchronizes the time among multiple devices.
Configure Router C's local clock as a reference source, with the stratum level 2.
•
• Configure Router C to operate in multicast server mode and send multicast messages from
GigabitEthernet 2/0/1.
Configure Router D and Router A to operate in multicast client mode and receive multicast messages
•
through their respective GigabitEthernet 2/0/1.
