# 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.
