and synchronizes the time among multiple devices.
• Configure Router C's local clock as a reference source, with the stratum level 2.
Configure Router C to operate in broadcast server mode and send broadcast messages from
•
GigabitEthernet 2/0/1.
Configure Router B and Router A to operate in broadcast client mode and receive broadcast
•
messages through their respective GigabitEthernet 2/0/1.
