Configuration procedure
1. Set the IP address for each interface as shown in Figure 34 . (Details not shown.)
2. Configure Router C:
# Enable the NTP service.
system-view
[RouterC] ntp-service enable
# Specify the local clock as the reference source, with the stratum level 2.
[RouterC] ntp-service refclock-master 2
# Configure Router C to operate in multicast server mode and send multicast messages through
Ethernet 1/1.
[RouterC] interface ethernet 1/1
[RouterC-Ethernet1/1] ntp-service multicast-server
3. Configure Router D:
# Enable the NTP service.
system-view
[RouterD] ntp-service enable
# Configure Router D to operate in multicast client mode and receive multicast messages on
Ethernet 1/1.
[RouterD] interface ethernet 1/1
[RouterD-Ethernet1/1] ntp-service multicast-client
4. Verify the configuration:
# Because Router D and Router C are on the same subnet, Router D can receive multicast messages
from Router C without being enabled with the multicast function and can synchronize to Router C.
Display the NTP status of Router D after clock synchronization.
[RouterD-Ethernet1/1] display ntp-service status
Clock status: synchronized
Clock stratum: 3
System peer: 3.0.1.31
Local mode: bclient
Reference clock ID: 3.0.1.31
Leap indicator: 00
