Dillon,
By leaving the dialer-group command off, the interface will
always drop after the idle-timeout expires due to the fact that since no
traffic is defined as interesting (no dialer-list is bound to the
interface since the dialer-group command is left off), the idle-time is
never being reset. If you do not want the interface to drop due to the
lack of interesting traffic, set the dialer idle-timeout to 0.
Also as a side note, you'll make answering your questions a lot
easier if you post your configurations when you post a question.

Hi, Ed:
Where is the Guideline from? Based on it, if I want to make a called
party on R1, I should set NO "dialer-group x", then all traffice change
to uninteresting, right? Then the only way for it, is just set "dialer
idle-timeout 0".
Any advice?
TIA
