interface and the NTP server coexist in this VPN.
■ If multiple VPNs have been configured on the PE and you want to synchronize
the PE to a PE or CE in one of these VPNs, you need to provide vpn-instance
vpn-instance-name in your command.
■ If you include vpn-instance vpn-instance-name in the undo ntp
unicast-server command, the command will remove 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 will remove
the NTP server with the IP address of ip-address in the public network.
