3.4.4 Configuring NTP Multicast Mode

I. Networking Requirements
Configure SecPath 3 clock as NTP master clock, and its stratum to 2. SecPath 3
sends multicast messages through the interface Ethernet 1/0/0. SecPath 4 and
SecPath 1 monitor multicast messages from respective interface Ethernet 1/0/0.

As shown in
III. Configuration Procedure
1) Configuring SecPath 3
# Configure local clock as NTP master clock, and its stratum to 2.
<SecPath3> system-view
[SecPath3] ntp-service refclock-master 2
# Enter interface Ethernet 1/0/0 view.
[SecPath3] interface ethernet 1/0/0
# Configure SecPath 3 as a multicast server.
[SecPath3-Ethernet1/0/0] ntp-service multicast-server
2) Configuring SecPath 4
