Hi
1) The question says SW1 and R5 should get the clock from BB3.
It also mentioned if BB3 is failed, then the clock should sync between
SW1 and R5. And the configuration shows the ntp peer command only on
R5 pointing SW1.
Why there is no ntp peer command on SW1 peering R5 ? If there is no
such command on SW1 then if BB3 fails time will not be sync with the
peer right ?
2) I intentionally made BB3 not reachable from R5 and now i do not
know how to verify whether the clock is syncling from Sw1 or not...
Here is the ntp status but no where it says it sync with SW1... Also
deb ntp di dnot show anything.
Is this expected ?
