Hi San,
The nature of dialer watch checking the routing table for
the watched route is controlled by the "dialer
idle-timeout" command. So, each time the idle-timer
expires the routing table is checked for the watched route
to see if it exists or not.
The command "dialer watch-list 1 delay disconnect 30" adds
a 30 sec delay to the process of disconnect after it's
discovered that the watched route (via original source) is
in the routing table.
To shorten the time, you'd need to decrease the idle timer
so that it checks for the watched route on a more frequent
basis.
