Ntp-Service Ipv6 Source - HPE FlexNetwork 10500 Series Network Management And Monitoring Command Reference

If you have configured the device to operate in IPv6 multicast server mode on an interface with the
command, do not add the interface to any aggregate group. To add the interface to an aggregate
group, remove the configuration of the command.
Examples
# Configure the device to operate in IPv6 multicast server mode and send IPv6 NTP multicast
messages on VLAN-interface 1 to the multicast address FF21::1, using key 4 for encryption.
<Sysname> system-view
[Sysname] interface vlan-interface 1

ntp-service ipv6 source

Use ntp-service ipv6 source to specify a source interface for IPv6 NTP messages.
Use undo ntp-service ipv6 source to restore the default.
Syntax
ntp-service ipv6 source interface-type interface-number
undo ntp-service ipv6 source
Default
No source interface is specified for IPv6 NTP messages. The device automatically selects the
source IP address for IPv6 NTP messages. For more information, see RFC 3484.

Parameters

Usage guidelines
If you specify a source interface for IPv6 NTP messages, the device uses the IPv6 address of the
source interface as the source address to send IPv6 NTP messages. Consequently, the destination
address of the IPv6 NTP response messages is the address of the source interface.
When the device responds to an IPv6 NTP request, the source IPv6 address of the NTP response is
always the IPv6 address of the interface that has received the IPv6 NTP request.
If you do not want the IPv6 address of an interface on the local device to become the destination
address for response messages, use the command to specify another interface as the source
interface for IPv6 NTP messages.
The source interface for IPv6 NTP messages can also be specified in the following ways:
•
In NTP client/server mode, if you have specified the source interface for IPv6 NTP messages in
the ntp-service ipv6 unicast-server command, the specified interface acts as the source
interface for IPv6 NTP messages.
