R3303-HP HSR6800 Routers Network Management and Monitoring Configuration Guide

Figure 29 Network diagram

Configuration procedure

1. Set the IP address for each interface as shown in Figure 29. (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 multicast server mode and send multicast messages through

GigabitEthernet 2/0/1.

[RouterC] interface gigabitethernet 2/0/1

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

3. Configure Router D:

# Configure Router D to operate in multicast client mode and receive multicast messages on

GigabitEthernet 2/0/1.

<RouterD> system-view

[RouterD] interface gigabitethernet 2/0/1

[RouterD-GigabitEthernet2/0/1] ntp-service multicast-client

Because Router D and Router C are on the same subnet, Router D can receive the multicast

messages from Router C without being enabled with the multicast functions and can be

synchronized to Router C.

# Display the NTP status of Router D after clock synchronization.

[RouterD-GigabitEthernet2/0/1] display ntp-service status
