Description
Use the
ntp-service
unicast-server
command to designate an NTP server for the device.
Use the
undo ntp-service
unicast-server
command to remove an NTP server designated for the device.
By default, no NTP server is designated for the device.
NOTE:
•
To synchronize the PE to a PE or CE in a VPN, provide
vpn-instance
vpn-instance-name in your
command.
•
If you include
vpn-instance
vpn-instance-name 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
vpn-instance
vpn-instance-name in this command, the command removes the NTP server with
the IP address of
ip-address in the public network.
