[RouterC] ntp-service unicast-server 10.0.0.1 authentication-keyid 42
Step 5 On RouterD, specify RouterB to be the NTP server of RouterD.
<RouterD> system-view
[RouterD] ntp-service authentication enable
[RouterD] ntp-service authentication-keyid 42 authentication-mode md5 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 configurations, the clock on RouterB can be synchronized with the clock on RouterA.
View the NTP status on RouterB and find that the clock synchronized. The stratum of the clock
is 3, one stratum lower than that on RouterA.
[RouterB] display ntp-service status
clock status: synchronized
clock stratum: 3
reference clock ID: 2.2.2.2
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 configurations, the clock on RouterC can be synchronized with the clock on RouterB.
View the NTP status on RouterC and find that the clock is synchronized. The stratum of the
clock is 4, one stratum lower than that on RouterB.
