IPv6 NTP client/server mode configuration example
Network requirements
As shown in Figure 9:
• Configure the local clock of Device A as a reference source, with the stratum level 2.
• Configure Device B to operate in client mode and Device A to be used as the IPv6 NTP server
for Device B.
Figure 9 Network diagram
Configuration procedure
1. Set the IP address for each interface, and make sure Device A and Device B can reach each
other, as shown in Figure 9. (Detail
s not shown.)
2. Configure Device A:
# Enable the NTP service.
