[c-nsp] NTP Server

[Annu Roopa]

Bill,
 
When i wrote "reliable" i was NOT referring to the NTP Server itself as a reliable source
 for other clients or peers.I was referring to how reliable are Cisco boxes as NTP server
 for an large enterprise (though it will work is it a good design).
 
Yes, i do agree with u when there are multiple sources for a client it will check for
 reliabilty and also the stratum level and synch with lowest level.
 
PS: Steve u may find this link useful. Some good discussions on this forum.

Most ntp servers and some clients permit you to monitor several servers. 
The ntp clients then will analyze the status of each server, and 
synchronize to the most accurate reliable server. So if the Cisco is not 
available, or is unreliable, it will not be used unless all more reliable 
ones are unavailable.
