Switch C and Switch D are on the same network segment; Switch A is on another network
segment; Switch F connects the two network segments.
As the NTP broadcast server, Switch C uses the local clock as the NTP master clock, which
is a stratum-3 clock. Switch C sends broadcast packets through VLANIF10, namely,
GigabitEthernet1/0/0.
Switch D uses VLANIF10, namely, GigabitEthernet1/0/0, to listen to the broadcast packets.
Switch A uses VLANIF20, namely, GigabitEthernet1/0/0, to listen to the broadcast packets.
NTP authentication needs to be enabled.

Configure Switch C as the NTP broadcast server.
Configure Switch A and Switch D as the NTP broadcast clients.
Configure NTP authentication on Switch A, Switch C, and Switch D.
