NTP Peer vs NTP Server

March 23, 2008 @ 1:09 pm · Filed under CCIE Study

With peers, nobody has authoritative time. That means, you might think it’s 1pm and I may think it’s 2pm, but we have no idea who is right so BOTH of us will adjust our time (max of 2 minutes each jump) until we finally compromise.
With client/server, the server actually has the authority, so clients will jump their time no matter how far off it is.

Hello, I went through the documentation to identify what is the difference between NTP server and NTP peer statements. The only difference I could find is that ntp peer allows both hosts to sync with each others while ntp server allows the host only to sync with the time server. THe question is when should i use the peer and when should I use the server when the question specifies to sync with BB1? Thanks for the calrification, Regards,
