X.X.X.X: Multicast IP address, which is a Class D address. The default address
is 224.0.1.1.
authentication-keyid: Defines the ID authentication key.
keyid: ID number used when transmitting messages to the multicast clients in
the range of 1 to 4294967295.
ttl: Defines the life span of the multicast packet.
ttl-number: Life span of the multicast packet in the range of 1 to 255.

Description
Using the ntp-service multicast-server command, you can configure the NTP
multicast server mode. Using the undo ntp-service multicast-server
command, you can remove the NTP multicast server mode.
By default, no multicast service is configured, the IP address is 224.0.1.1 and
the version number is 3.
This command is used to specify an interface on the local device to transmit
NTP multicast packets. The local device is run in server (multicast-server)
mode, which acts as the multicast server to transmit multicast messages
periodically to the multicast clients.
Example
Configure Ethernet 1/0/0 to transmit NTP multicast messages. The multicast
address is 244.0.1.1, encrypted by No.4 key. The NTP version number is set to
3.
