Configuration procedure
1. Set the IP address for each interface as shown in Figure 53 . (Details not shown.)
2. Configure SecPath C:
# Specify the local clock as the reference source, with the stratum level of 2.
<SecPathC> system-view
[SecPathC] ntp-service refclock-master 2
# Configure SecPath C to operate in multicast server mode and send multicast messages through
GigabitEthernet 0/1.
[SecPathC] interface GigabitEthernet 1/1
[SecPathC-GigabitEthernet0/1] ntp-service multicast-server
3. Configure SecPath D:
# Configure SecPath D to operate in multicast client mode and receive multicast messages on
GigabitEthernet 0/1.
<SecPathD> system-view
[SecPathD] interface GigabitEthernet 0/1
[SecPathD-GigabitEthernet0/1] ntp-service multicast-client
Because SecPath D and SecPath C are on the same subnet, SecPath D can receive the multicast
messages from SecPath C without being enabled with the multicast functions and can be
synchronized to SecPath C.
# View the NTP status of SecPath D after clock synchronization.
