3) Configure S5600-2.
# Enter system view.
<S5600-2> system-view
[S5600-2]
# Enter VLAN-interface 2 view.
[[S5600-2] interface Vlan-interface 2
# Configure S5600-2 to be a multicast client.
[S5600-2-Vlan-interface2] ntp-service multicast-client
The above configuration configures S5600-1 and S5600-2 to listen to multicast
packets through their VLAN interface 2, and Quidway3 to advertise multicast packets
through VLAN interface 2. Because S5600-2 does not reside in the same network
segment with Quidway3, S5600-2 cannot receive multicast packets sent by Quidway3,
while S5600-1 is synchronized to Quidway3 after receiving multicast packets sent by
Quidway3.
