Usage guidelines
When you specify an NTP server for the device, the device is synchronized to the NTP server, but the NTP
server is not synchronized to the device.
To synchronize the PE to a PE or CE in a VPN, provide vpn-instance vpn-instance-name in your
command.
If you include the vpn-instance vpn-instance-name option in the undo ntp-service unicast-server
command, the command removes the NTP server with the IP address of ip-address in the specified VPN.
If you do not include the vpn-instance vpn-instance-name option in this command, the command removes
the NTP server with the IP address of ip-address in the public network.
Examples
# Specify NTP server 10.1.1.1 for the device, and configure the device to run NTP version 4.
<Sysname> system-view
[Sysname] ntp-service unicast-server 10.1.1.1 version 4
