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 this command, the device listens to IPv6 NTP messages with the destination address
as the specified multicast address and is synchronized based on the received IPv6 NTP messages.
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
Related commands
ntp-service ipv6 multicast-server
ntp-service ipv6 multicast-server
Use ntp-service ipv6 multicast-server to configure the device to operate in IPv6 NTP multicast server
mode and use the current interface to send IPv6 NTP multicast packets.
Use undo ntp-service ipv6 multicast-server to remove the configuration.
Syntax
ntp-service ipv6 multicast-server ipv6-multicast-address [ authentication-keyid keyid | ttl ttl-number ] *
undo ntp-service ipv6 multicast-server ipv6-multicast-address
Default
The device does not operate in any NTP association mode.
Views
VLAN interface view, Layer 3 Ethernet interface view
Predefined user roles

Parameters
ipv6-multicast-address: Specifies an IPv6 multicast IP address. An IPv6 multicast client and server must be
configured with the same multicast address.
authentication-keyid keyid: Specifies the key ID to be used for sending multicast messages to multicast
clients, where keyid is in the range of 1 to 4294967295. If this option is not specified, the local device
cannot synchronize clients enabled with NTP authentication.
ttl ttl-number: Specifies the TTL of NTP multicast messages, where ttl-number is in the range of 1 to 255.
The default value is 16.
Usage guidelines
After you configure this command, the device periodically sends NTP messages to the specified IPv6
multicast address.
