Configuration procedure
1. Set the IP address for each interface as shown in Figure 19 . (Details not shown.)
2. Configure Router C:
# Specify the local clock as the reference source, with the stratum level 2.
system-view
[RouterC] ntp-service refclock-master 2
# Configure Router C to operate in broadcast server mode and send broadcast messages through
Ethernet 1/1.
[RouterC] interface ethernet 1/1
[RouterC-Ethernet1/1] ntp-service broadcast-server
3. Configure Router A:
# Configure Router A to operate in broadcast client mode and receive broadcast messages on
Ethernet 1/1.
system-view
[RouterA] interface ethernet 1/1
[RouterA-Ethernet1/1] ntp-service broadcast-client
4. Configure Router B:
# Configure Router B to operate in broadcast client mode and receive broadcast messages on
Ethernet 1/1.
system-view
[RouterB] interface ethernet 1/1
[RouterB-Ethernet1/1] ntp-service broadcast-client
Router A and Router B get synchronized upon receiving a broadcast message from Router C.
# Take Router A as an example. Display the NTP status of Router A after clock synchronization.
[RouterA-Ethernet1/1] display ntp-service status
Clock status: synchronized
Clock stratum: 3
Reference clock ID: 3.0.1.31
