Network requirements
As shown in
, Router C functions as the NTP server for multiple devices on different network
segments and synchronizes the time among multiple devices. Router B authenticates the reference source.
•
Router C’s local clock is to be used as a reference source, with the stratum level 3.
•
Router C operates in broadcast server mode and sends broadcast messages from Ethernet 1/1.
•
Router A and Router B operate in broadcast client mode and receive broadcast client through
Ethernet 1/1.
•
Configure NTP authentication on both Router B and Router C.
