Configuration procedure

1. Set the IP address for each interface as shown in Figure 31. (Details not shown.)

2. Configure Router A:

# Configure Router A to operate in NTP broadcast client mode and receive NTP broadcast

messages on GigabitEthernet 2/0/1.

<RouterA> system-view

[RouterA] interface gigabitethernet 2/0/1

[RouterA-GigabitEthernet2/0/1] ntp-service broadcast-client

3. Configure Router B:

# Enable NTP authentication on Router B. Configure an NTP authentication key, with the key ID of

88 and key value of 123456. Specify the key as a trusted key.

<RouterB> system-view

[RouterB] ntp-service authentication enable

[RouterB] ntp-service authentication-keyid 88 authentication-mode md5 123456

[RouterB] ntp-service reliable authentication-keyid 88

# Configure Router B to operate in broadcast client mode and receive NTP broadcast messages on

GigabitEthernet 2/0/1.

[RouterB] interface gigabitethernet 2/0/1

[RouterB-GigabitEthernet2/0/1] ntp-service broadcast-client

4. Configure Router C:

# Specify the local clock as the reference source, with the stratum level 3.

<RouterC> system-view

[RouterC] ntp-service refclock-master 3

# Configure Router C to operate in NTP broadcast server mode and use GigabitEthernet 2/0/1 to

send NTP broadcast packets.

[RouterC] interface gigabitethernet 2/0/1

[RouterC-GigabitEthernet2/0/1] ntp-service broadcast-server
