But does each peer server (in comparison with others two servers) serve same or different time to clients ? I don't understand if these 3 peer servers synchronize themselves among them establishing a share time.

For redundancy do you think that it's necessary to change stratum level for each peer server (server A,B,C) of my lan ? (for instance server A stratum 10, server B stratum 11, server C stratum 12). What do you suggest me ? _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
