Parameters
server-name: Specifies the host name of the NTP server, a case-insensitive string of 1 to 253
characters.
ipv6-address: Specifies the IPv6 address of the NTP server.
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 network, do not specify this option.
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. If this option is not specified, the local device
and NTP server do not authenticate each other.
source interface-type interface-number: Specifies the source interface for IPv6 NTP messages. If
the specified IPv6 NTP server address is not a link local address, the source IPv6 address for IPv6
NTP messages sent by the local device to the NTP server is the IPv6 address of the specified source
interface. If the specified IPv6 NTP server address is a link local address, the IPv6 NTP messages
are sent from the specified source interface, and the source address of the messages is the link local
address of the interface. The interface-type interface-number argument represents the interface type
and number. If you do not specify an interface, the device automatically selects the source IPv6
address of IPv6 NTP messages. For more information, see RFC 3484.
Usage guidelines
When you specify an IPv6 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 the vpn-instance vpn-instance-name option
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 the command, the
command removes the NTP server with the IP address of ip-address in the public network.
If the specified IPv6 address of the NTP server is a link local address, you must specify the source
interface for NTP messages and cannot specify a VPN for the NTP server.
Examples
# Specify the IPv6 NTP server 2001::1 for the device.
<Sysname> system-view
[Sysname] sntp ipv6 unicast-server 2001::1
