Dialer Watch

Hi guys,

Assume dialer watch is configured to trigger an isdn call if the primary
connection goes down.

It seems to me that there are 2 time intervals that determine how long after
the primary connection goes down dialer watch kicks in:

a) how often dialer watch checks the route table for the watched route and

b) how long after the primary connection goes down before a route learned via
the primary connection is removed from the route table.

So far, does everyone agree with this?

In addition, once the dialer watch has triggered a call, I know that dialer
watch checks the route table everytime the dialer idle-timeout expires.

But, what about before dialer watch has triggered a call? How often does
dialer watch check the route table in this case?

I assume that the dialer idle-timeout timer isn't active before isdn has an
active call. Is this true?

Here's the problem.

Let's say I want dialer watch to trigger a call in the shortest amount of time
possible.

Depending the routing protocol being used, what is the shortest amount of
time?

Thanks, Tim
