Parameters
ipv6-multicast-address: Specifies an IPv6 multicast 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. The value range for the ttl-number argument
is 1 to 255, and the default is 16.
Usage guidelines
After you configure the command, the device periodically sends NTP messages to the specified IPv6
multicast address.
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 GigabitEthernet 2/0/1 to the multicast address FF21::1, using key 4 for encryption.
