Hello.
In our infrastructure we had some ntp clients that don't have access to the world and so they are configured to use only 2 servers (by the way, the other have 2 more options). In reality both servers are the same, but with different IPs. >From time to time some clients configured in this way lose their reference for some short period. I know how NTP works (http://www.ntp.org/ntpfaq/NTP-s-algo-real.htm#Q-NTP-ALGO), and so this seems to be caused by both 2 servers or just 1 of them not have survived. But both the clients and the servers are physically in the same place, and even if they aren't in the same IP network, they are in the same LAN with just a switch or two between them (delay is between 1 and 2 ms). And the question is why this does happen in the local network? Aren't they close enough in order to avoid a split? Given that, I have changed the configuration, and now they only use 1 server, but that is not a good solution. Any alternative for the configuration? More servers, most likely virtual servers? Thank you. Nuno Pereira G9Telecom
