Dmitry,
The Symetric passive mode and active mode can get confusing sometimes. If
you have time, read RFC 1129. It gives a clear indication of the intended
purpose of Peers & Servers & Clients. In brief :
Peers are intended in an environment where they are allowed to synchronise
with each other, a Server mode doesnt allow for this to happen, a Client can
'only' synchronise 'with' a server (and not vice versa). So in essence a
Peer is somewhere in between a Client and SErver.
How/Where can you use it ? Well, in a distribution layer you could have
'peers' who can synchronise with each other, when a server is unreachable.
Remember a Server would be at a lower stratum number hence more preferable,
in absence of which, the Peers can choose to synchronise with either/each
other.
And last but not least, the most important rule, no client/peer will
synchronise with the Server/Peer if that server/peer is in turn not
synchronised with itself.
