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. 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

messages on VLAN-interface 1 to the multicast address FF21::1, using key 4 for encryption.
