corresponding to an interface, execute the undo ntp-service ipv6 inbound enable command on
the interface.
Examples
# Disable VLAN-interface 1 from processing IPv6 NTP messages.
<Sysname> system-view

Parameters
ipv6-multicast-address: Specifies an IPv6 multicast IP address. An IPv6 broadcast client and an IPv6
broadcast server must be configured with the same multicast address.
Usage guidelines
After you configure the command, the device listens to IPv6 NTP messages using the specified
multicast address as the destination address. It is synchronized based on the received IPv6 NTP
messages.
If you have configured the device to operate in IPv6 multicast client mode on an interface by using
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 client mode and receive IPv6 NTP multicast
messages with the destination FF21::1 on VLAN-interface 1.
<Sysname> system-view
[Sysname] interface vlan-interface 1
[Sysname-Vlan-interface1] ntp-service ipv6 multicast-client ff21::1
