Step 2 Configure the NTP multicast server.
# Configure the local clock of RouterA as the NTP primary clock, and set the clock stratum to
2.
<RouterA> system-view
[RouterC] ntp-service refclock-master 2
# Configure RouterA as the NTP multicast server that sends NTP multicast packets from
GE1/0/0.
[RouterA] interface gigabitethernet 1/0/0
[RouterA-GigabitEthernet1/0/0] ntp-service multicast-server
[RouterA-GigabitEthernet1/0/0] quit
Step 3 Configure the NTP multicast client RouterB on a network segment the same as that of the NTP
server.
# Configure RouterB as the NTP multicast client that listens to the NTP multicast packets from
interface GE1/0/0.
<RouterB> system-view
[RouterB] interface gigabitethernet 1/0/0
[RouterB-GigabitEthernet1/0/0] ntp-service multicast-client
[RouterB-GigabitEthernet1/0/0] quit
Step 4 Configure the NTP multicast client RouterC on a network segment different from that of the
server.
# Configure RouterC as the NTP multicast client that listens to the NTP multicast packets from
interface GE1/0/0.
<RouterC> system-view
[RouterC] interface gigabitethernet 1/0/0
[RouterC-GigabitEthernet1/0/0] ntp-service multicast-client
[RouterC-GigabitEthernet1/0/0] quit
Step 5 Verify the configuration.
After the preceding configuration is complete, RouterB and RouterC can synchronize their
clocks to the clock of RouterA.
# Check the NTP status of RouterB, and you can find that the clock status is "synchronized",
indicating that the synchronization is complete. The stratum of the clock is 3, which is one
stratum lower than that of the clock of the server RouterA.
[RouterB] display ntp-service status
clock status: synchronized
clock stratum: 3
reference clock ID: 10.1.1.2
nominal frequency: 60.0002 Hz
actual frequency: 60.0002 Hz
clock precision: 2^18
clock offset: 0.66 ms
root delay: 24.47 ms
root dispersion: 208.39 ms
peer dispers ion: 9.63 ms
reference time: 12:17:21.773 UTC Mar 7 2012(C7B7F851.C5EAF25B)
