IPv6 NTP multicast mode configuration example
Network requirements
As shown in Figure 35 , Router C functions as the NTP server for multiple devices on different network
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 IPv6 multicast server mode and sends out IPv6 NTP multicast messages from
Ethernet 1/1.
• Router D and Router A operate in multicast client mode and receive IPv6 multicast messages
through their respective Ethernet 1/1.

Configuration procedure
1. Set the IP address for each interface as shown in Figure 35 . (Details not shown.)
