R3303-HP HSR6800 Routers Network Management and Monitoring Configuration Guide

NTP broadcast mode configuration example

Network requirements

As shown in Figure 28, Router C functions as the NTP server for multiple devices on a network segment

and synchronizes the time among multiple devices.

• Router C’s local clock is to be used as a reference source, with the stratum level 2.

• Router C operates in broadcast server mode and sends broadcast messages from GigabitEthernet

2/0/1.

• Router B and Router A operate in broadcast client mode and receive broadcast messages through

their respective GigabitEthernet 2/0/1.

Configuration procedure

1. Set the IP address for each interface as shown in Figure 28. (Details not shown.)

2. Configure Router C:

# Specify the local clock as the reference source, with the stratum level 2.

<RouterC> system-view

[RouterC] ntp-service refclock-master 2

# Configure Router C to operate in broadcast server mode and send broadcast messages through

GigabitEthernet 2/0/1.

[RouterC] interface gigabitethernet 2/0/1

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

3. Configure Router A:

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

GigabitEthernet 2/0/1.

<RouterA> system-view

[RouterA] interface gigabitethernet 2/0/1

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

4. Configure Router B:
