4.6.4 Example for Configuring the Common NTP Multicast Mode
Networking Requirements
As shown in Figure 4-5,
l Switch C and Switch D are on the same network segment; Switch A is on another network
segment; Switch F connects the two network segments.
l As the NTP multicast server, Switch C uses the local clock as the NTP master clock, which
is a stratum-2 clock. Switch C sends multicast packets through VLANIF 10, namely,
GigabitEthernet0/0/1.
l Switch D uses VLANIF 10, namely, GigabitEthernet0/0/1, to listen to the multicast packets.
l Switch A uses VLANIF 20, namely, GigabitEthernet0/0/1, to listen to the multicast packets.
