# Specify RouterA as the NTP server of RouterB, and use the configured authentication key.
[RouterB] ntp-service unicast-server 10.2.2.2 authentication-keyid 42
Step 4 # Specify on RouterC that RouterB functions as the NTP server of RouterC.
<RouterC> system-view
[RouterC] ntp-service authentication enable
[RouterC] ntp-service authentication-keyid 42 authentication-mode hmac-sha256
Hello
[RouterC] ntp-service reliable authentication-keyid 42
[RouterC] ntp-service unicast-server 10.0.0.1 authentication-keyid 42
Step 5 # Specify on RouterD that RouterB functions as the NTP server of RouterD.
<RouterD> system-view
[RouterD] ntp-service authentication enable
[RouterD] ntp-service authentication-keyid 42 authentication-mode hmac-sha256
Hello
[RouterD] ntp-service reliable authentication-keyid 42
[RouterD] ntp-service unicast-server 10.0.0.1 authentication-keyid 42
Step 6 Verify the configuration.
After the preceding configuration is complete, RouterB can synchronize its clock with the clock
of RouterA.
# Check the NTP status of RouterB, and you can find that the clock status is "synchronized",
indicating that the synchronization is complete. The stratum of the clock is 3, which is one
stratum lower than that of the clock of the server RouterA.
[RouterB] display ntp-service status
clock status: synchronized
clock stratum: 3
reference clock ID: 10.2.2.2
nominal frequency: 60.0002 Hz
actual frequency: 60.0002 Hz
clock precision: 2^18
clock offset: 3.8128 ms
root delay: 31.26 ms
root dispersion: 74.20 ms
peer dispersion: 34.30 ms
reference time: 11:55:56.833 UTC Mar 2 2006(C7B15BCC.D5604189)
After the preceding configuration is complete, RouterC can synchronize its clock with the clock
of RouterB.
# Check the NTP status of RouterC, and you can find that the clock status is "synchronized",
indicating that the synchronization is complete. The stratum of the clock is 4, which is one
stratum lower than that of the clock of the server RouterB.
[RouterC] display ntp-service status
clock status: synchronized
clock stratum: 4
reference clock ID: 10.0.0.1
nominal frequency: 60.0002 Hz
actual frequency: 60.0002 Hz

# Check the NTP status of RouterD, and you can find that the clock status is "synchronized",
indicating that the synchronization is complete. The stratum of the clock is 4, which is one
stratum lower than that of the clock of the server RouterB.
