Ntp-Service Ipv6 Unicast-Server - HP 6125XLG Command Reference Manual

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.
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. If this option is not specified, the local device and the peer do
not authenticate each other.
priority: Specifies the peer specified by ip-address or peer-name as the first choice under the same
condition.
source interface-type interface-number: Specifies the source interface for IPv6 NTP messages. If the
specified passive peer address is not a link local address, the source IPv6 address for IPv6 NTP messages
sent by the local device is the IPv6 address of the specified source interface. If the specified passive peer
address is a link local address, the IPv6 NTP messages are sent from the specified source interface. The
interface-type interface-number argument represents the interface type and number. If you do not specify
an interface, the device automatically selects the source IPv6 address of IPv6 NTP messages. For more
information, see RFC 3484.
Usage guidelines
When you specify an IPv6 passive peer for the device, the device and its IPv6 passive peer can be
synchronized to each other. If their clocks are in synchronized state, the clock with a high stratum level is
synchronized to the clock with a lower stratum level.
To synchronize the PE to a PE or CE in a VPN, provide 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 ipv6 unicast-peer
command, the command removes the symmetric-passive peer with the IPv6 address of ipv6-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 IPv6 address of ipv6-address in the public
network.
Examples
# Specify the device with the IPv6 address of 2001::1 as the symmetric-passive peer of the device, and
specify the source interface for IPv6 NTP messages as VLAN-interface 1.
<Sysname> system-view
[Sysname] ntp-service ipv6 unicast-peer 2001::1 source vlan-interface 1
