Configuration procedure
1. Set the IP address for each interface as shown in Figure 32 . (Details not shown.)
2. Configure Device A:
# Enable the NTP service.
system-view
[DeviceA] ntp-service enable
# Specify the local clock as the reference source, with the stratum level 3.
[DeviceA] ntp-service refclock-master 3
3. Configure Device B:
# Enable the NTP service.
system-view
[DeviceB] ntp-service enable
# Specify Device A as the IPv6 NTP server of Device B.
[DeviceB] ntp-service ipv6 unicast-server 3000::34
4. Configure Device C:
# Enable the NTP service.
system-view
[DeviceC] ntp-service enable
# Specify the local clock as the reference source, with the stratum level 2.
[DeviceC] ntp-service refclock-master 2
# Configure Device B as an IPv6 symmetric passive peer.
[DeviceC] ntp-service ipv6 unicast-peer 3000::35
5. Verify the configuration:
# After the configuration, Device B has two time servers Device A and Device C. Device C has a
lower stratum level than Device A, so Device B selects Device C as a reference clock to synchronize
to Device C. After synchronization, view the status of Device B. The output shows that Device B has
been synchronized to Device C.
