Router C and Router D are in the same network segment; Router A is in another network
segment; Router F connects with the two network segments.
Router C functions as an NTP multicast server and its clock is a primary NTP clock with
the stratum being 2. Multicast packets are sent out from GE 1/0/0.
Router D and Router A sense the multicast packets respectively on GE 1/0/0 of them.
