The output shows that an association has been set up between Device B and Device A, and Device
B and Device C
IPv6 NTP symmetric active/passive mode
configuration example
Network requirements
•
As shown in
Figure 11
, Device C has a clock more accurate than Device A. Set the local clock of
Device A as a reference source, with the stratum level 3.
•
Set the local clock Device C as a reference source, with the stratum level 2.
•
Configure Device B to operate in client mode and specify Device A as the IPv6 NTP server of Device
B.
•
Configure Device C to operate in symmetric-active mode and specify Device B as the IPv6 passive
peer of Device C.
