Dialer-list is the one that will idle make the line drop when not in use for
a particular time. And when it reaches the idle time then dialer-watch says
"No No No !! dont u know that the primary route is still missing" . and
after that it refresh that timer.
u can check this with "show dialer interface xxxx "
and do a "debug dialer packet" and "debug dialer event".
Watch closely the timer idle in the show dialer interface xxxx . it will
rest again if the primary route is not present.
By the way the orignal post that was that , i am not getting this to work on
12.0(9) . My primary route is learnt dynamically and it is not wathcing it.
Is this is an IOS issue or i am missing something..
