authentication-key key-number type type value password;
number
is the key number,
type

Configuring the Router or Switch to Listen for Broadcast Messages Using NTP
When you are using NTP, you can configure the local router or switch to listen for
broadcast messages on the local network to discover other servers on the same subnet
by including the
broadcast-client statement at the [edit system ntp] hierarchy level:
[edit system ntp]
broadcast-client ;
When the router or switch detects a broadcast message for the first time, it measures
the nominal network delay using a brief client-server exchange with the remote server.
It then enters
broadcast client mode, in which it listens for, and synchronizes to, succeeding
broadcast messages.
To avoid accidental or malicious disruption in this mode, both the local and remote
systems must use authentication and the same trusted key and key identifier.

Configuring the Router or Switch to Listen for Multicast Messages Using NTP
When you are using NTP, you can configure the local router or switch to listen for multicast
messages on the local network to discover other servers on the same subnet by including
the
multicast-client statement at the [edit system ntp] hierarchy level:
[edit system ntp]
multicast-client <address>;
When the router or switch receives a multicast message for the first time, it measures
the nominal network delay using a brief client-server exchange with the remote server.
It then enters
multicast client mode, in which it listens for, and synchronizes to, succeeding
multicast messages.
You can specify one or more IP addresses. (You must specify an address, not a hostname.)
If you do, the router or switch joins those multicast groups. If you do not specify any
addresses, the software uses
224.0.1.1
