Description
When configuring NTP, the node can be configured to receive broadcast packets on a given subnet.
Broadcast and multicast messages can easily be spoofed, thus, authentication is strongly
recommended. If broadcast is not configured then received NTP broadcast traffic will be ignored. Use
the show command to view the state of the configuration.
The no form of this command removes the address from the configuration.
Parameters router router-name — Specifies the router name used to receive NTP packets.
interface ip-int-name — Specifies the local interface on which to receive NTP broadcast packets.
authenticate — Specifies whether or not to require authentication of NTP PDUs. When enabled,
