HPE FlexNetwork MSR3012 User Manual

106
interface. If the specified IPv6 NTP server address is a link local address, the IPv6 NTP messages
are sent from the specified source interface, and the source address of the messages is the link local
address of the 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 NTP server for the device, the device is synchronized to the IPv6 NTP
server, but the IPv6 NTP server is not synchronized to the device.
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-server
command, the command removes the NTP server with the IP address of ip-address in the specified
VPN. If you do not include the vpn-instance vpn-instance-name option in the command, the
command removes the NTP server with the IP address of ip-address in the public network.
If the specified IPv6 address of the NTP server is a link local address, you must specify the source
interface for NTP messages and cannot specify a VPN for the NTP server.
Examples
# Specify the IPv6 NTP server 2001::1 for the device.
<Sysname> system-view
[Sysname] ntp-service ipv6 unicast-server 2001::1
