Example:
Organization network not connected to Internet.
Time given by HW clocks (GNSS / radio clock / rubidium osc or whatever
else) and distributed on a dedicated L2 PTP network.
NTP servers pool connected to the PTP network and to the organization
network.
Each server use the GM on the PTP network.
Each server in the pool are declared as ntp source for the other servers.
Orphan mode is activated.
With ntpd, as long as my refclock is running all work normally.
If I lost my PTP switch, orphan mode kick in and all the servers in the
pool serve a coherent time.
With chrony, as refclocks are not taken into account in the orphan mode
decision (status of the refclock, stratum) and as I am not using other
externals NTP sources I am always in orphan mode.
