Good point, Sorry for the wrong information.

Subject: Re: Dialer Watch and Dialer-group
With dialer watch a dialer idle timeout of zero is not really needed on the
remote side, since it will not be the one "watching" and will not bring up
the call. For the ease of configuration for dialer watch I always put the
least amount if configuration on the remote side( ie ppp multilink(if
needed), dialer load-threshold, encap ppp, ppp authe pap or chap, and the
username and password) The only reason for a dialer group on the remote
side and the dialer idle-timeout to be set to zero would be if you were
doing ppp callback w/dialer watch, then it would make sure that the remote
end would not disconnect the call based on the idle-timeout.
HTH,

Hi,
Cisco Doc UniverCD and Solie's book brings examples using Dialer Watch with
dialer-group.
But the same Cisco Doc says:
"Once the secondary link is up, at the expiration of each idle timeout,
the primary link is rechecked"
http://www.cisco.com/univercd/cc/td/doc/product/software/ios113ed/113t/113t_
2/dwatch.htm#xtocid1516510
Tests shows it is not necessary to use dialer-group.
Is there another reason to use diaeler-group in this case?
I am using dialer idle-timeout 0 on the remote router.
idle-timeout on local router is reset while the primary link is down by
Dialer Watch.
