ntp-service ipv6 unicast-server
Use ntp-service ipv6 unicast-server to specify an IPv6 NTP server for the device.
Use undo ntp-service ipv6 unicast-server to remove an IPv6 NTP server specified for the device.

[ authentication-keyid keyid | priority | source interface-type interface-number ] *
undo ntp-service ipv6 unicast-server { server-name | ipv6-address } [ vpn-instance vpn-instance-name ]
Default
No IPv6 NTP server is specified for the device.

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. It must be a unicast address, rather than a
multicast address.
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.
priority: Specifies this NTP server as the first choice under the same condition.
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 IPv6 NTP server,
but the IPv6 NTP server is not synchronized to the device.
