R211x-HP Flexfabric 11900 Network Management and Monitoring Command Reference

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.
To synchronize the PE to a PE or CE in a VPN, specify the vpn-instance vpn-instance-name option in the
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.
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] ntp-service ipv6 unicast-server 2001::1
