I use linuxconf (in Networking, Client Tasks, PPP) for general config of 
PPP (ppp0 in my case) then refine it in the scripts. Make sure Set default 
route (in Customize under ppp0 config) is toggled on.

demand (which implies persist), nopersist, holdoff, idle etc can be 
specified in the /etc/ppp/options file in RH6.1 (see man pppd for 
explanations of the options). One options suite which works for me is:

lock
demand
idle 600
holdoff 600
nopersist

You've no doubt found chat-ppp in /etc/sysconfig/network-scripts.

I choose to kick off /etc/sysconfig/network-scripts/ifup-ppp ifcfg-ppp0 
from /etc/rc.d/rc.local to bring the interface up at boot time for a 
dial-on-demand machine. (I also bring up IP masquerading at this time, but 
that's another issue).

Hope this moves you one step closer.
