Step 3 Configure the NTP multicast client Router D in the same network segment as that of the NTP
server.
# Configure Router D to be an NTP multicast client. Router D senses the NTP multicast packets
on GE 1/0/0.
<RouterD> system-view
[~RouterD] interface gigabitethernet 1/0/0
[~RouterD-GigabitEthernet1/0/0] ntp-service multicast-client
[~RouterD-GigabitEthernet1/0/0] commit
Step 4 Configure the NTP multicast client Router A in a network segment different from that of the
NTP server.
# Configure Router A to be an NTP multicast client. Router A senses the NTP multicast packets
on GE 1/0/0.
<RouterA> system-view
[~RouterA] interface gigabitethernet 1/0/0
[~RouterA-GigabitEthernet1/0/0] ntp-service multicast-client
[~RouterA-GigabitEthernet1/0/0] commit
Step 5 Verify the configuration.
After the configurations, the clock on Router D can be synchronized to the clock on Router C.
The clock on Router A, however, fails to be synchronized because Router A and Router C are
in different network segments and Router A cannot sense the multicast packets sent from
Router C.
Check the NTP status on Router D and you can find that the clock status is "synchronized". That
is, clock synchronization completes. The stratum of the clock on Router D is 3, one stratum
lower than that on Router C.
