Dear All,
I have a couple of questions about the NTP output from NTP associations detail:-
1) What does "insane, invalid" mean? The server is reachable and a valid NTP sever.
Command output attached
2) The cisco router is attached to a the NTP source shows the source as an NTP Stratum 3 clock, but the router and all other routers show it as a Stratum 4. Yet the router connected to a Stratum 2 clock shows it as a stratum 2 entry.
Command output attached
We had a failure of the secondary NTP server, but lost all NTP updates.
