RE: dialer watch idle time out

Justin,
I'm watching both routes in the watch-list.

I didn't have allot to go on other than the example on the DOC CD. In the exam
ple, they have three prefixes in the watch-list, but only one of them is used i
n a dialer map.

The document says:
1 Whenever a watched route is deleted, Dialer Watch checks to see if there is a
t least one valid route for any of the defined watched IP addresses.
2 If no valid route exists, the primary line is considered down and unusable.

Since it will only dial the backup if ALL the routes are missing, it doesn't se
em to matter which network is in dialer map.

No other working configs have been posted since I got on the list in July. I f
ound one in the archives. It uses a single route in the watch-list.

My config works. The problem turned out to be on the called router. It was ha
nging up after the idle-timeout because it didn't see the traffic as interestin
g. The router with the dialer watch config always called right back.

Charles

What routes are you watching?

Why do you have 156.43.41.0/24 in your watch-list, but no dialer map for
this network?

Anyone used dialer watch much?

I got it to work with OSPF & EIGRP with 2500s running 12.0(9). It looks
like it has an idle timeout of 90 seconds. At the end of the 90 seconds, it
does something. If the primary link comes up during the 90 seconds and
stays up, the dial session will drop at the end of the 90 seconds.

If the primary is down at the 90 second mark, the dial session still drops,
but redials immediately. Is this the common/expected behavior?

Here is debug dialer from the router with dialer watch:
