3. Configure Firewall D:
# Configure NTP authentication.
<FirewallD> system-view
[FirewallD] ntp-service authentication enable
[FirewallD] ntp-service authentication-keyid 88 authentication-mode md5 123456
[FirewallD] ntp-service reliable authentication-keyid 88
# Configure Firewall D to operate in the NTP broadcast client mode.
[FirewallD] interface gigabitethernet 0/1
[FirewallD-GigabitEthernet0/1] ntp-service broadcast-client
Now, Firewall D can receive broadcast messages through GigabitEthernet 0/1, and Firewall C
can send broadcast messages through GigabitEthernet 0/1. Upon receiving a broadcast
message from Firewall C, Firewall D synchronizes its clock to that of Firewall C.
# View the NTP status of Firewall D after clock synchronization.
