xntpd daemon

[Tarek]

I configured 1 ntp server..i want configure 2 ntp peers and then all clients pointing to ntp peers. How should i configure ntp peers? Do i have to put in the /etc/rc.config.d/netdaemons in NTPDATE_SERVER the IP address of the master? In this case, if the master is down, how can peers synchronize?
I issued the command on the ntp master:
ntpq -p and under st (stratum) i have the value 3. But if i issue ntpq -c rv i have written stratum=4..so which is my real stratum??
