5.7.4 Example for Configuring NTP Multicast Mode

Networking Requirements
As shown in
(LAN). RouterA is directly synchronized to a standard clock by radio.
The clocks of all routers on the network need to be synchronized to the standard clock.

RouterA
Configuration Roadmap
As is required by the user, the NTP protocol is used to synchronize clocks. The configuration
roadmap is as follows:
1.
2.
3.
Procedure
Step 1 Configure an IP address for each interface according to
# Configure an IP address for the interface on RouterA.
<Huawei> system-view
[Huawei] sysname RouterA
[RouterA] interface gigabitethernet 1/0/0
[RouterA-GigabitEthernet1/0/0] ip address 10.1.1.1 24
[RouterA-GigabitEthernet1/0/0] quit
For details about the configurations of RouterB and RouterC, see "Configuration Files".

Configure RouterA as the primary time server, use the local clock as the NTP primary
clock, and set the clock stratum to 2.
Configure RouterA as the NTP multicast server that sends multicast packets from interface
GE1/0/0.
Configure RouterB and RouterC as NTP multicast clients. RouterB uses GE1/0/0 to listen
to the multicast packets. RouterC uses GE1/0/0 to listen to the multicast packets.
