Parameters
vpn-instance vpn-instance-name: Specifies the VPN to which the NTP server belongs, where
vpn-instance-name is a case-sensitive string of 1 to 31 characters. If the NTP server is on the public
network, do not specify this option.
server-name: Host name of the NTP server, which is a string of 1 to 20 characters.

where keyid ranges from 1 to 4294967295.
priority: Specifies this NTP server as the first choice under the same condition.
source-interface interface-type interface-number: Specifies the source interface for NTP messages. In an
NTP message the local device sends to the NTP server, the source IP address is the primary IP address of
this interface. interface-type interface-number represents the interface type and number.
version number: Specifies the NTP version, where number ranges from 1 to 3 and defaults to 3.
Description
Use ntp-service unicast-server to designate an NTP server for the device.
Use undo ntp-service unicast-server to remove an NTP server designated for the device.
By default, no NTP server is designated for the device.
To synchronize the PE to a PE or CE in a VPN, provide vpn-instance vpn-instance-name in the command.
If you include vpn-instance vpn-instance-name 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 vpn-instance vpn-instance-name in this command, the command removes the NTP server with the
IP address of ip-address in the public network.
