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.
