I have a truetime NTP server on the network and I point to it with several routers. When I do a show ntp associations detail and sh ntp status, I get stratum information indicating that the truetime is at stratum 1 and the router pointing to it is at stratum 2. If I set up several peers and make one of them preferred, how will another router be selected to provide NTP info to me? Will the best stratum get selected or will the preferred peer? How do the routers know what stratum they are at? If I create an NTP master, will that peer get selected over the preferred peer in the event that lower stratum routers are not available in the peer list? thx
