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.
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 that 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, where
number
is in the range of 1 to 3 and defaults to 3.
Description
Use the
ntp-service
unicast-peer
command to designate a symmetric-passive peer for the device.
Use the
undo ntp-service
unicast-peer
command to remove the symmetric-passive peer designated for the
device.
By default, no symmetric-passive peer 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-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
vpn-instance
vpn-instance-name 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 device,
configure the device to run NTP version 3, and specify the source interface of NTP messages as
VLAN-interface 1.
