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.

<DeviceA> 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.

<DeviceB> 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.

<DeviceC> 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.

[DeviceB] display ntp-service status
