Use undo ntp-service unicast-peer to remove the symmetric-passive peer designated for the device.
Syntax
ntp-service unicast-peer [ vpn-instance vpn-instance-name ] { ip-address | peer-name }
[ authentication-keyid keyid | priority | source-interface interface-type interface-number | version
number ] *
undo ntp-service unicast-peer [ vpn-instance vpn-instance-name ] { ip-address | peer-name }
Default
No symmetric-passive peer is designated for the device.

Parameters
vpn-instance vpn-instance-name: Specifies the VPN to which the symmetric-passive peer belongs, where
vpn-instance-name is a case-sensitive string of 1 to 31 characters. If the symmetric-passive peer is on the
public network, do not specify this option.
ip-address: IP address of the symmetric-passive peer. It must be a unicast address, rather than a
broadcast address, a multicast address or the IP address of the local clock.
peer-name: Host name of the symmetric-passive peer, a string of 1 to 20 characters.
authentication-keyid keyid: Specifies the key ID to be used for sending NTP messages to the peer, where
keyid is in the range of 1 to 4294967295.
priority: Specifies the peer designated by ip-address or peer-name as the first choice under the same
condition.
source-interface interface-type interface-number: Specifies the source interface for NTP messages. In an
NTP message the local device sends to its peer, the source IP address is the primary IP address of this
interface. The interface-type interface-number argument represents the interface type and number.
version number: Specifies the NTP version, where number is in the range of 1 to 4 and defaults to 3.
Usage guidelines
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-peer command,
the command removes the symmetric-passive peer 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 symmetric-passive peer with the IP address of ip-address in the public network.
Examples
# Designate the device with the IP address of 10.1.1.1 as the symmetric-passive peer of the local device,
configure the local device to run NTP version 3, and specify the source interface of NTP messages as
GigabitEthernet 0/1.
