Parameters
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN 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

ip-address: IP address of the NTP server. It must be a unicast address, rather than a broadcast address,
a multicast address or the IP address of the local clock.
server-name: Host name of the NTP server, a string of 1 to 20 characters.
authentication-keyid keyid: Specifies the key ID to be used for sending NTP messages to the NTP server,
where keyid is in the range of 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. The value range for the number argument is 1 to 4, and the
