ntp-service unicast-peer

Use ntp-service unicast-peer to designate a symmetric-passive peer for the device.
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 MPLS L3VPN 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. interface-type interface-number represents the interface type and number.
version number: Specifies the NTP version. The value range for the number argument is 1 to 4, and the
default is 3.
Usage guidelines
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-peer command, the
command removes the symmetric-passive peer with the IP address of ip-address in the specified VPN. If
